A basic level Quantum Mechanics book for beginners in UG & PG Physics. In fact Quantum Mechanics is not Mathematics. But many teachers even now treating this subject as Mathematics. It has its own concepts and ideas. Without this understanding one cannot excel in Quantum Mechanics. Inadequacy of classical physics led to Quantum Mechanics and it was able to prove the mechanics in microlevel. Mathematics can be used as a language for understanding. After estimating wave function, the physics behind it has to be understood. For this authors tried to avoid mathematical steps. But included all necessary steps. This book is highly helpful for students to understand the basics of Quantum Mechanics.

This publication is about quantum mechanics and about real phenomena hidden by the formalism of quantum mechanics. Quantum mechanics assumes the existence of quantum waves and superposition states. However, the existence of these cannot be experimentally demonstrated. A new way to explain formation of the interference fringes created by particles without assuming the existence of quantum waves is used to reveal the origin of Bohr’s philosophy and the Copenhagen interpretation of quantum mechanics. This new approach is also used to show that EPR, delayed choice, quantum eraser and which-way experiments do not test quantum mechanics adequately. The presented text gives an approach how to look at quantum mechanics and see beyond its formalism. This gives ideas for new tests. The publication is directed to researchers interested in fundamentals of quantum mechanics but also to all physicists who can appreciate mystery and strangeness of this theory.

Quantum field theories are quite difficult. The successes achieved by using quantum field theories are rather limited because in these theories one faces various difficulties. Later Dirac introduced an alternative process to quantize the fields. He introduced Hamiltonian equations of motion from Lagrangian to describe the laws of mechanics and gravitation. It has wide application in classical mechanics, quantum mechanics and quantum field theory, as well as in general relativity etc. One may deal with Hamiltonian in general frameworks as well as oscillatory systems.

Quantum particles are the main theme ideas of quantum mechanics. We cannot imagine the matter of quantum mechanics without considering these microparticles and their motion. According to German Physic’s Max Planck, classical mechanics fails to study the motion of micro particle like electron then new modern physics named Quantum Mechanics grows at the end of nineteen century and Planck expressed it in Einstein’s hypothesis of light quanta. This book demonstrates the motion of quantum particle like electron with the help of some Mathematical form of Schrodinger wave equation. Here we use The Variational iterative method which reduces the size of calculations. This method provides a well-organized and much effective method for handling this nonlinear behaviour.

The purpose of this work is to retrace the steps that were made by scientists of ‘900, like Bohr, Schrodinger, Heisenberg, Pauli, Dirac, for the formulation of what today represents the modern quantum mechanics and that, within two decades, put in question the classical physics. In this context, the study of the electronic structure of hydrogen atom has been the main starting point for the formulation of the theory and, till now, remains the only real case for which the quantum equation of motion can be solved exactly. The results obtained by each theory will be discussed critically, highlighting limits and potentials that allowed the further development of the quantum theory.

The present book contains one hundred and sixty problems, most of them simple, in nonrelativistic quantum mechanics. Some of these problems were used previously by the authors in their courses at the Moscow Institute of Engineering and Physics. However, the majority were drawn up or selected in the course of work on the book. This book is designed for physics students who are studying quantum mechanics approximately at the level of D.I.Blokhintsev's book or Part II of "Theoretical Physics" by A.S.Kompaneyts. A number of problems is intended primarily for students who are beginning to specialize in theoretical physics and who are partially familiar with the contents of "Quantum Mechanics" by L.D.Landau and Ye.M.Lifshits. Some problems illustrate individual theoretical questions which have scarcely been considered in textbooks: sudden and adiabatic changes; Heisenberg representation of operators; probability relations in addition of momenta; isotopic spin; parity; and others. The authors have tried to use relatively elementary mathematical tools of quantum mechanics to facilitate use of the book by nontheoretical physicists. With a few exceptions, the authors have not included in this book problems which are considered in sufficient detail in the basic textbooks mentioned above and in the problem book on quantum mechanics written by V.G.Levich. Therefore, this book should be regarded chiefly as an auxiliary textbook in the study of the above books.

This book presents a complete review of the theory of nonlinear quantum mechanics and which differs totally from the original discipline of quantum mechanics as well as the studies the nature of microscopic particles under action of the nonlinear interactions in the systems; which give numerous new and interesting properties and rules of motions of the particles, such as wave-corpuscle duality and localization, and which discusses the applications of theory as relates to condensed matter, polymers, and biological systems. It is intended for researchers, teachers, graduate students and upper-level undergraduate students. The so-called discipline of nonlinear quantum mechanics (NLQM) is, in reality, only a theory for studying the properties and motion of microscopic particles (MIPs) in nonlinear physical systems. It was so named in relation to the concept of quantum mechanics established by Bohr, Heisenberg, Schrodinger and numerous others. The latter deals only with the properties and motion of microscopic particles in linear systems without nonlinear interactionh and will, here-in-after, referred to as linear quantum mechanics (LQM). The following topics are covered in 6 chapters i

The main topic of this book is quantum mechanics, as the title indicates. It specifically targets those topics within quantum mechanics that are needed to understand modern semiconductor theory. It begins with the motivation for quantum mechanics and why classical physics fails when dealing with very small particles and small dimensions. Two key features make this book different from others on quantum mechanics, even those usually intended for engineers: First, after a brief introduction, much of the development is through Fourier theory, a topic that is at the heart of most electrical engineering theory. In this manner, the explanation of the quantum mechanics is rooted in the mathematics familiar to every electrical engineer. Secondly, beginning with the first chapter, simple computer programs in MATLAB are used to illustrate the principles. The programs can easily be copied and used by the reader to do the exercises at the end of the chapters or to just become more familiar with the material. Many of the figures in this book have a title across the top. This title is the name of the MATLAB program that was used to generate that figure. These programs are available to the reader. Appendix D lists all the programs, and they are also downloadable at http://booksupport.wiley.com

This book is destined for scientific workers and professors in the field of quantum mechanics and quantum theory of collisions, students and post-graduate students and all interested in quantum mechanics, quantum field theory and nuclear physics. The book contains the chapter of fundamental quantum mechanics and quantum field theory – on time as a quantum observable for systems with continuous and discrete spectra. In its completed form this book could not be written up to now due to a number of the mathematical problems. Some mathematicians had been known the solution of these problems in the field of operator theory in Hilbert spaces for systems with continuous energy spectrum. But practically these problems were unknown for almost of all physicists, with the exception of the author and his friend. Overcoming these and other mathematical problems permitted finally to develop and apply the methods of time analysis of quantum processes and write this book. Moreover, in it there are exposed also many applications of time analysis of quantum processes and paradoxes for tunneling and collisions (nuclear reactions)which were elaborated by author, partly together with colleagues.

In this work we study two non-classical features of quantum compound systems, namely, entanglement and indistinguishability using logical and algebraic techniques. First, we study improper mixtures from a quantum logical and geometrical point of view. This is done by extending the von Neumann lattice of propositions in order to include improper mixtures as atoms of the new lattice. Then, we study the problem of quantum non-individuality. We use a quantum structure which is a modification of Zermelo-Frenkel set-theory based on quantum mechanics, namely, Quasi-set Theory (Q). Using Q we develop a new formulation of quantum mechanics which does not uses first order identity on its logical bases. These constructions answer interesting discussions posed in the literature.

The book contains the developments in quantum mechanics as well as the basic concepts of quantum formalism in simple terms. Quantum Mechanics is the science of motion of atomic and sub atomic Particles. Experimental measurements for atomic and molecular systems shows that an electron moving around the nucleus of an atom has only a discrete set of values of energy. Rotational motion of particle is of great interest in atomic and molecular problems. For single particle executing such a motion, the Schrodinger equation can be solved. Graduate and senior undergraduate students in Physics, or engineering students, who intend to do research in Physics should find this book useful.

The aim of the present work is twofold: On one hand it considers the treatment of time observables in quantum mechanics. In particular, it is concerned with the application of a particular spin-boson detector model to arrival and passage times. Thus, it helps to illuminate the fundamental issue of how to treat time in quantum mechanics. In this course some interesting questions of quantum measurement theory are discussed by particular examples. On the other hand it explores the possibility of extending the quantum jump approach to a model beyond its original, quantum optical framework. It also examines by means of numerical examples whether the quantum jump approach, which employs a continuum of bath modes, promises to provide a good approximation to situations where one actually has to deal with a number of discrete bath modes.

Kinetic energy is a non-zero positive value in many cases of bound states, when a wave function is a real-valued one and there are no visible motion and flux. This can be understood, using expansion of the wave function into Fourier integral, that is, on the basis of virtual plane waves. This explanation was proposed by the author in 1963 when the author had been studying Quantum Mechanics. Self-action in a system of elementary particles, charged with elementary charges, is discussed in detail. This self-action is not taken in account in Quantum Mechanics, because otherwise experimental data (including data on atomic spectra) could not be theoretically explained. In Quantum Mechanics sometimes there is an electrostatic field without any electrostatic energy stored in it, and electrostatic negative energy with no charge and no electrostatic field, like in a positronium. Criteria for low-dimensional quantum movements are derived, quantum and classical rotations of modern objects are regarded. Simplified theory of polarons and bipolarins is proposed, and simple explanation of coexistence of zero angular momentum and non-zero magnetic moment in many-electron system is discussed.

In quantum mechanics, there are many counter-intuitive phenomena comparing with classical mechanics. In this book, we consider the two methods to compare the classical and the quantum systems. One is to quantitatively characterize the counter-factual phenomena in quantum mechanics related to the classical logic. We show that the weak value, which was initiated and developed by Yakir Aharonov and his colleagues and is an experimental accessible quantity, can characterize them by a simple example. We propose that the weak value is interpreted as a fundamental quantity to reformulate the quantum theory to obtain that the weak value can be derived from the observable-independent probability space in the sense of the Kolmogorov probability theory. The other content is the discrete time quantum walk (DTQW), which is defined as a quantum-mechanical analogue of the random walk. We obtain the analytical expression for the limit distribution of the one-dimensional DTQW with a two-dimensional coin. Under the simple decoherence model, we show that the DTQW is linearly related to the classical random walk. We also obtain that the DTQW can be taken as the quantum dynamical simulator.

The book presents some aspects of noncommutative quantum mechanics and field theory. It introduces the basic mathematical formalism of noncommutative quantum mechanics. In particular it reviews the procedure of Weyl quantization which is an useful technique for translating an ordinary field theory into a noncommutative one. Then as a preliminary exercise, it is demonstrated how noncommuting structures can be obtained in the first place by exploiting the reparametrization symmetry of particle models. Then it goes to investigate various other problems in these areas, namely, the construction of a one parameter family of noncommutative quantum theories dual to a commutative theory. The book should be useful to anyone interested in knowing the basic aspects of this fascinating field of noncommutative quantum physics.

Key advancements in the understanding of the fundamental and universal Quantum Mechanics now lead the way towards realizing the long outstanding resolution to the idea that "Quantum Mechanics is capable of yielding its own interpretation". One seemingly simple consideration today opens new doors to significant progress and sensibility, and that is the the consideration of the quantum mechanical view of the decomposition of System into subsystems. Progress in the understanding of subsystems and how they conspire to make a whole is presented in terms of Quantum Correlations Relativity, the Parallel Occurrence of Decoherence, Preferred Local Structures for Bipartite Decompositions of a two-mode Open System, and the discovery of a limitation of the Nakajima-Zwanzig Projection Method in Open Systems Theory. Ultimately, we can now impose a limitation on, and forcefully question the long term viability of the Everett Interpretation.

The computing power in terms of speed and capacity of today's digital computers has improved tremendously in the last decade. This improvement came mainly due to a revolution in manufacturing technology by developing the ability to manufacture smaller devices and by integrating more devices on a single die. Further development of the current technology will be restricted by physical limits since it won't be possible to shrink devices beyond a certain size. Eventually, classical electrical circuits will encounter the barrier of quantum mechanics. The laws of quantum mechanics can be used for building computing systems that work on the principles of quantum mechanics. Thus quantum computing has drawn the interest of many top scientists in the world. Ion Trap technology is one of the most promising prospective technologies for building quantum computers. This technology allows the placement of qubits - ions in 1-, 2- and 3-dimensional regular structures. This book presents efficient algorithms and methodologies for designing reversible quantum circuits.

This book explores the way in which quantum theory has become central to our understanding of the behaviour of atoms and molecules and the way in which this underlies so many of the experimental measurements we make, how we interpret those experiments and the language which we use to describe our results. It attempts to provide an account of the quantum theory and some of its applications to chemistry. The subject matter develops as follows: Chapter 1 considers the place of theory in science, emphasising in particular the significance of hypotheses, postulates and laws; Chapter 2 gives an account, in approximately historical sequence, of the development of the quantum theory paying particular attention to the emerging experimental data and the new theoretical concepts developed for their interpretation; Chapters 3 and 4 describe some fundamental details of the theory with explanations and simple, chemically–relevant examples. Emphasis is laid on what we can and cannot know and comparisons with classical, macroscopic mechanics are made wherever possible; The remaining chapters (5–12) describe the quantum mechanics involved in the important techniques (especially IR, NMR and electronic spectroscopy) and theoretical concepts (the chemical bond, molecular magnetism) that underlie our modern views of molecular structure and function. Here also calculations relevant to chemical problems are described in detail; Many aspects of the mathematics of quantum theory are placed in the 10 appendices which also provide a valuable source of reference material on units, conversion factors and mathematical functions useful in quantum–mechanical calculations; Most chapters include boxed text that expands on and explains the material in the main text and problems are presented at the end of each chapter. This book is for researchers working on experimental aspects of chemistry and the allied sciences at all levels, from advanced undergraduates to experienced research project leaders, wishing to improve, by self–study or in small research–orientated groups, their understanding of the ways in which quantum mechanics can be applied to their problems. The book also aims to provide useful background material for teachers of quantum mechanics courses and their students.

The possibility of using quantum sets in quantum mechanics was considered long ago. In this book we consider fractal Cantorian sets and emphasize the role of the empty set in physics and the crucial difference between the zero and the empty set. The quantum particle is represented by a Cantorian zero set while the quantum wave is represented by an empty Cantorian set. The new quantum entanglement theory is presented generalizing Einstein’s energy equation to an effective quantum gravity formula predicting accurately the actually measured cosmic energy content of the universe. The energy given by Einstein’s famous formula consists of two parts. The first part is the ordinary energy of the quantum particle modelled by the topology of the zero set. The second part is the dark energy of the quantum wave modelled by the topology of the empty set.

Quantum mechanics (QM) is latently present in the life of electrical engineers already, since the hardware of todays information technology - from electrical data processing, through interconversion of electronic and optical information, to data storage and visualization - works on QM principles. New developments in micro- and opto-electronics and the advent of quantum information processing will soon make the active understanding of QM unavoidable for engineers, too. Unfortunately, the principles of QM can only be formulated mathematically, so even introductory books on the subject are mostly rather abstract. This book, written mainly for BSc students, tries to help the reader by showing "QM in action", demonstrating its surprising effects directly in applications, like lighting technology, lasers, photo- and solar cells, flash memories and quantum bits. While the axioms and basic concepts of quantum mechanics are introduced without compromises, the math is kept at a level which is required from electrical engineers anyhow. Computational work is spared by the use of Applets which also visualize the results. Among the host of other didactic features are learning objectives, chapter summaries, self-testing questions, and problems with solutions, while two appendices summarize the knowledge in classical physics and mathematics which is needed for this book.

This two-volume book series is an attempt to formulate a consistent relativistic quantum theory of interacting charged particles. The major construction will be undertaken in the second volume. Our goal in this first volume is to prepare the reader for that effort. Here we will introduce notation, terminology, and basic ideas of relativistic quantum theories. Our discussion will proceed systematically and, more or less traditionally, from the principle of relativity and postulates of measurements to the renormalization in quantum electrodynamics. This will cover material usually found in textbooks on quantum field theory. However, we will choose particles (rather than fields) as our basic ingredients. Quantum fields will be regarded as mere mathematical tools, which are convenient for building relativistically invariant and cluster separable particle interactions. The reader is expected to have a good grasp of non-relativistic quantum mechanics.

Based on the law of energy conservation, the author shows that, the steady state electronic motion around a given nucleus in a non-circular orbit, depicts a rest mass variation, though the overall relativistic energy remains constant. This is, in no way, conflicting with the usual quantum mechanical approach. Quite on the contrary it provides one with the possibility of bridging the Special Theory of Relativity and Quantum Mechanics, to finally achieve a natural symbiosis between these two disciplines, and furthermore, elucidating the “quantum mechanical weirdness”, simply based on the mere law of relativistic energy conservation. The author developed his theory, originally, vis-a-vis gravitational bodies in motion with regards to each other; hence, it is comforting to have both the atomic scale and the celestial scale described on just the same conceptual basis. The approach leads to the de Broglie relationship, and superluminal speeds, yet excluding any exchange of energy, making the basis of quantum mechanics.

"As Towfic Shomar argues, if we are looking for quantum description that gives very accurate predictions about superconducting phenomena we can make do with the "phenomenological" equations of Ginzburg-Landau model, These equations are phenomenological in two senses: First, they are not derived by constructing a model to which a Hamiltonian is assigned, but rather are justified by an ad hoc combination of considerations from thermodynamics, electro-magnetism and quantum mechanics itself. Second, the model does not give us any representation of the causal mechanisms that might be responsible for superconductivity."

Quantum computers use aspecific physical implementation to gain a computational advantage over conventionalcomputers. Properties called superposition and entanglement may, in some cases, allow anexponential amount of parallelism. Also, special purpose machines like quantumcryptographic devices use entanglement and other peculiarities like quantum uncertainty.Quantum computing combines quantum mechanics, information theory, and aspects ofcomputer science. The field is a relatively new one that promises secure data transfer,dramatic computing speed increases, and may take component miniaturization to itsfundamental limit.

Mostly, in the topics of mathematical tools, quantum mechanics assimilates in a manner with matrices theory that and its operability and ability differentiates as a pure theory is difficult. The subject of this study is that to show the ability of this theory in different discussions and particular differences of its solution methods with other theories. Principally, applied mathematics in Dirac – Jordan transformation theory is particular and differs with the mathematics present in theorems and relations of wave and matrices theories . Encountering with wave and matrices theories maybe implies, at least, applied mathematics in these theories gives certain relation between them, but there is not the case of Dirac – Jordan transformation theory. Quantum state of a particle in a given time, in Schrodinger’s wave theory, was defined by wave function . Probabilistic interpretation of this wave function requires that its square could be integrated, and this leads to study Hilbert, H space.

Revision with unchanged content. Quantum mechanics has radically changed our classical conception of information and communication. The elementary unit of information, the "bit", is replaced by the "qubit" which is a superposition of zero and one. Several qubits can be entangled among each other so that each qubit alone is neither zero nor one, nor any superposition of it. If qubits are used to encode messages then these "quantum messages" do not behave like ordinary ones. They cannot be compressed without loss of information, and the process of reading disturbs their content. Such apparent weaknesses, however, give rise to a revolutionary concept of secure communication... This book reviews the basic concepts of quantum information, develops a theoretical framework for variable-length quantum messages, derives some theorems, and introduces a novel secure communication scheme, the so-called "Ping-Pong protocol", which has attracted some interest in the scientific community and has recently been experimentally realized. The reader should be roughly familiar with probability theory, linear algebra and basic quantum mechanics.

Understanding and simulating quantum operations on a classical computer has different approaches and is modeled in different ways. However, the most repute ways are Quantum Turing Machine, Network Model or circuit model of connected gates and Quantum Programming Language. Many simulators do exist that varies in many features such as implementation languages, target platforms, paradigms, visuality, and applied quantum algorithms. There was a developmental trade-off between the simplicity and the functionality of the simulator. The goals and research activities are outlined as follows: First, surveying the quantum computing world, its characteristics, issues, problems, and challenges. Second, surveying the existing quantum simulators, illustrating representative simulators of major approaches, their features, and functionalities. Third, introducing a framework to provide the power of quantum computing , while insisting the simplicity and high usability.

The electronic devices have such impact on our lives that it is impossible to imagine our present society without them. Nowadays, the spatial dimensions and working times of the commercial electronic devices are arraying at nanometer and picoseconds scales, so that their performance has to be understood with quantum mechanics. Quantum electron transport theories and their application to electron device modeling have matured into a well-established ?eld with active research, intensive software development, and vast commercial applications. On the other hand, Bohmian mechanics is a well established theory for computing quantum phenomena. Based on this formalism, in this book, a general versatile and time-dependent 3D electron transport simulator for nanoelectronic devices named BITLLES is developed (http://europe.uab.es/bitlles). In particular, the simulator takes advantage of the use of (Bohmian) conditional wavefunctions to tackle, both, the quantum many-body and the quantum sequential measurement problems, which become of fundamental importance to understand the noise and high-frequency behavior of state-of-the-art nanoelectronic devices.

Introduces number operators with a focus on the relationship between quantum mechanics and social science Mathematics is increasingly applied to classical problems in finance, biology, economics, and elsewhere. Quantum Dynamics for Classical Systems describes how quantum tools—the number operator in particular—can be used to create dynamical systems in which the variables are operator-valued functions and whose results explain the presented model. The book presents mathematical results and their applications to concrete systems and discusses the methods used, results obtained, and techniques developed for the proofs of the results. The central ideas of number operators are illuminated while avoiding excessive technicalities that are unnecessary for understanding and learning the various mathematical applications. The presented dynamical systems address a variety of contexts and offer clear analyses and explanations of concluded results. Additional features in Quantum Dynamics for Classical Systems include: Applications across diverse fields including stock markets and population migration as well as a unique quantum perspective on these classes of models Illustrations of the use of creation and annihilation operators for classical problems Examples of the recent increase in research and literature on the many applications of quantum tools in applied mathematics Clarification on numerous misunderstandings and misnomers while shedding light on new approaches in the field Quantum Dynamics for Classical Systems is an ideal reference for researchers, professionals, and academics in applied mathematics, economics, physics, biology, and sociology. The book is also excellent for courses in dynamical systems, quantum mechanics, and mathematical models.

Cavity quantum electrodynamics (CQED) features all unique characteristics of quantum mechanics, studying the strong interaction of single photons and atoms. The implementation of artificial superconducting atoms in high quality transmission line cavities realizes such a CQED setup in a solid state environment. This opens the field of quantum optics to embedded devices. Furthermore, the relatively simple fabrication of these devices makes them a promising candidate for the realization of a quantum information processor. In this architecture, macroscopic quantum circuits act as effective two- and three-level systems (qubits and qutrits) by employing the large non-linearity of a Josephson junction. They strongly couple to single photons in a one-dimensional superconducting cavity which inhibits radiative decay for the contained fragile states and at the same time acts as a readout device.

Over the past half century wires and logic gates in computers have halved in size every year and a half, creating a phenomenon known as the Moore’s law. As the size of computer components reduces towards the atomic scale, however, the classical laws of thermodynamics are no longer able to predict the real behavior of electronic devices. In this context, the theory of quantum mechanics becomes increasingly important to characterize how circuits operate. Quantum information is the theory of communication and computation born to study the potential arising from information encoded in elementary particles, such as photons. The essential goal of quantum information is to determine how the quantum laws ruling the peculiar phenomena happening at an atomic scale can be used to enhance the capabilities of computers and communication systems.

Quantum game theory is an interdisciplinary field. It combines two completely separate disciplines greatly developed by John von Neumann: game theory and quantum information theory. Like in classical game, in quantum game one can point out all basic notions that are used to define a classical game like a set of players, sets of strategies for the players and a payoff function. On the other hand all these notions are expressed with the use of mathematical methods for quantum information like linear operators and unit vectors of a complex Hilbert space in accordance with the postulates of quantum mechanics. This new approach to the description of a game constitutes its strict generalization. For example, quantum game theory allows one to write any finite strategic game in the language of linear algebra in such a way that a classical game and its quantum counterpart are indistinguishable from game theory point of view. However, the most interesting property is that quantum information methods can give new, impossible in the classical case, scenarios of the game. This book explores the way in which quantum theory has become central to our understanding of the behaviour of atoms and molecules and the way in which this underlies so many of the experimental measurements we make, how we interpret those experiments and the language which we use to describe our results. It attempts to provide an account of the quantum theory and some of its applications to chemistry. The subject matter develops as follows: Chapter 1 considers the place of theory in science, emphasising in particular the significance of hypotheses, postulates and laws; Chapter 2 gives an account, in approximately historical sequence, of the development of the quantum theory paying particular attention to the emerging experimental data and the new theoretical concepts developed for their interpretation; Chapters 3 and 4 describe some fundamental details of the theory with explanations and simple, chemically–relevant examples. Emphasis is laid on what we can and cannot know and comparisons with classical, macroscopic mechanics are made wherever possible; The remaining chapters (5–12) describe the quantum mechanics involved in the important techniques (especially IR, NMR and electronic spectroscopy) and theoretical concepts (the chemical bond, molecular magnetism) that underlie our modern views of molecular structure and function. Here also calculations relevant to chemical problems are described in detail; Many aspects of the mathematics of quantum theory are placed in the 10 appendices which also provide a valuable source of reference material on units, conversion factors and mathematical functions useful in quantum–mechanical calculations; Most chapters include boxed text that expands on and explains the material in the main text and problems are presented at the end of each chapter. This book is for researchers working on experimental aspects of chemistry and the allied sciences at all levels, from advanced undergraduates to experienced research project leaders, wishing to improve, by self–study or in small research–orientated groups, their understanding of the ways in which quantum mechanics can be applied to their problems. The book also aims to provide useful background material for teachers of quantum mechanics courses and their students.
