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.

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.

Problem of existence of quantum waves

4468 руб.
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.

Matrix Quantum Mechanics and 2D String Theory

String theory is the most promising candidate for the theory unifying all interactions including gravity. Since it has an extremely difficult dynamics, many important insights have come from the study of its low-dimensional versions. A particularly interesting case is 2D string theory, which has a very rich structure, but at the same time is solvable. Its complete solution in the simplest linear dilaton background was obtained using its representation as Matrix Quantum Mechanics, which provides a very powerful technique and reveals the integrability hidden in the usual CFT formulation. This book presents a review of these results and extends them to non-trivial backgrounds of 2D string theory. It shows how MQM incorporates the perturbations changing the background, their integrability, and various results on correlation functions, thermodynamic behavior, structure of the target space and non-perturbative effects in the deformed background. The book is recommended for students and researchers working in theoretical and mathematical physics.

Essential Quantum Mechanics for Electrical Engineers

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 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 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.

Extended supersymmetry in quantum mechanics and self-dual gauge fields

We study certain new models of supersymmetric quantum mechanics. The explicit form of the corresponding superfield and component actions, as well as of the quantum Hamiltonians and supercharges is given. It is shown that the Hamiltonian H=D*D, where D is flat four-dimensional Dirac operator in an external self-dual gauge background, Abelian or non-Abelian, is supersymmetric with N=4 supersymmetry. A generalization of this Hamiltonian to the motion on a curved conformally flat four-dimensional manifold exists. For an Abelian self-dual background, the corresponding Lagrangian can be derived from certain harmonic superspace expressions. If the Hamiltonian involves a non-Abelian self-dual gauge field, one can construct the Lagrangian formulation of it by introducing auxiliary bosonic variables with Wess-Zumino type action. For a special class of such Lagrangians when the gauge group is SU(2) and the gauge field is expressed in the `t Hooft ansatz form, it is possible to give a superfield description using the harmonic superspace formalism. Independently, a similar system with N=4 supersymmetry in three dimensions also admits the superfield description.

To combine the formulas of GR and QM to calculate something, the same answer is always yielded: infinity, still unsolved. The issue of space-time curvature, Problem of quantization, Universe is non-local or local, particles are zero dimensional or what?, Background of space-time and matter, superposition of states and so on are few of unsolved problems of QM and Relativity. We have observed a relation between reciprocity and quantum statistics. Reciprocity may be a bridge between QM and Relativity which is a great unsolved problem. We have defined Reciprocal Symmetry and we have applied it to find an invariant under addition. This invariant quantity is either an upper bound of a set of quantities or a lower bound of the reciprocals of this set. The set bounded above together with this invariant quantity corresponds to Einstein’s postulate. we find that discreteness is directly related Einstein’s postulate or Lorentz transformation. We have seen that Reciprocals and reciprocal symmetry relate Einstein’s postulate and Lorentz transformation to discreteness, wave motion and Fermi-Dirac statistics. Reciprocal symmetry, therefore, relates quantum mechanics (QM) to relativity.

The book is essentially a result of the authors' attempt to generalize Dirac's elegant method of solving the eigenvalue problem of the linear harmonic oscillator by constructing raising and lowering operators. As such, students of elementary Quantum Mechanics will find Chapters II and III quite useful and illuminating. At many stages in the book the reader will find the power of the commutator algebra unfolding in an elegant manner, as in the original Dirac approach. See the lucid application of the technique to find the eigenvalues and eigenfunctions of the Kratzer oscillator algebraically A student of Advanced Quantum Mechanics will find, in Chapter III, an illustrious application of the celebrated Infeld-Hull factorization method to find a class of ladder operators which connect the eigenstates of a hierarchy of Hamiltonians like, but not the same as, the ones in Supersymmetric Quantum Mechanics. The book will be of interest to a large spectrum of students of Physics at the Master's degree level and graduate students entering a research career in Theoretical Physics and Quantum Chemistry.

"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."

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.

Superluminal Interaction as the Basis of 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.

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.

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.

Rarely, the authors of quantum mechanics books have discussed Dirac – Jordan transformation theory in abstract and pure form . 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.

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.

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.

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 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.

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.

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 Computation is an interdisciplinary field formed by the merge of quantum effect, information theory and algorithms. The future of computing lies with the quantum computers which may be a hypothetical paradigm but surely will be a reality very soon.This book describes about some quantum algorithms and programs which will prove as the foundation of quantum computers in the years to come.In quantum computers we exploit quantum effects to compute in ways that are faster or moreefficient than, or even impossible, on conventional computers. 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.

Application of quantum computing to game theory

4716 руб.
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.
