Principles Of Non Relativistic And Relativistic Quantum Mechanics

by K. D. KRORI, Principles Of Non Relativistic And Relativistic Quantum Mechanics Books available in PDF, EPUB, Mobi Format. Download Principles Of Non Relativistic And Relativistic Quantum Mechanics books, Quantum mechanics emerged as one of the greatest discoveries in science owing to pioneering work and individual contributions of eminent scientists—Planck, Einstein, Bohr, Compton, de Broglie, Schrodinger, Heisenberg, and Dirac—over a span of three decades from 1900 to 1930. Later, path integral formalism and quantum electrodynamics came through the work of Feynman. Still later, Weinberg and Salam developed the electroweak theory. The entire spectrum of both non-relativistic quantum mechanics and relativistic quantum mechanics has been covered in this book in a simple style to be truly beneficial to all levels of students. The book is organized into three parts. The first part describes the development of quantum theory, starting from Planck’s law to de Broglie hypothesis. The Schrodinger theory has been introduced with relevant logic. This part also includes the treatments of angular momentum, path integral formalism, two-electron systems and interaction of radiation with matter. The second part deals with relativistic quantum theory including Klein–Gordon and Dirac equations, Weyl’s neutrino theory, ending with gauge theory applied to Salam–Weinberg electroweak theory. The third part delves into the conceptual foundations of quantum mechanics, and Einstein–Bohr debate culminating in Bell’s inequality theorem. The book concludes with a discussion on three quantum interference effects in electromagnetic and gravitation fields each of which has a deep physical importance. Throughout, the book is suitably illustrated to clarify the concepts and contains worked-out problems as well as chapter-end exercises. This book is intended for undergraduate and postgraduate students of physics and chemistry.

Quantum Mechanics

by L D Landau, Quantum Mechanics Books available in PDF, EPUB, Mobi Format. Download Quantum Mechanics books, Quantum Mechanics, Third Edition: Non-relativistic Theory is devoted to non-relativistic quantum mechanics. The theory of the addition of angular momenta, collision theory, and the theory of symmetry are examined, together with spin, nuclear structure, motion in a magnetic field, and diatomic and polyatomic molecules. This book is comprised of 18 chapters and begins with an introduction to the basic concepts of quantum mechanics, with emphasis on the uncertainty principle, the principle of superposition, and operators, as well as the continuous spectrum and the wave function. The following chapters explore energy and momentum; Schrödinger's equation; angular momentum; and motion in a centrally symmetric field and in a magnetic field. Perturbation theory, spin, and the properties of quasi-classical systems are also considered. The remaining chapters deal with the identity of particles, atoms, and diatomic and polyatomic molecules. The final two chapters describe elastic and inelastic collisions. This monograph will be a valuable source of information for physicists.

Elements Of Non Relativistic Quantum Mechanics

by L Sobrino, Elements Of Non Relativistic Quantum Mechanics Books available in PDF, EPUB, Mobi Format. Download Elements Of Non Relativistic Quantum Mechanics books, This book presents the basic structure of quantum mechanics, the elements needed to properly understand the subject and its applications. It is written at a level which is intermediate between the standard graduate textbooks, which it intends to supplement, and the more advanced mathematical writings in the subject. Particular attention is given to the concepts of kinematical and dynamical symmetries. The unifying thread that links the study of particles and systems of particles is the connection between Galilean invariance and the fundamental observables of a system. The mathematical appendices on the Hilbert space, the theory of distributions and Dirac's formalism provide a mathematical basis which is adequate for many working theoretical physicists.

Principles Of Quantum General Relativity

by Eduard Prugove?ki, Principles Of Quantum General Relativity Books available in PDF, EPUB, Mobi Format. Download Principles Of Quantum General Relativity books, This monograph explains and analyzes the principles of a quantum-geometric framework for the unification of general relativity and quantum theory. By taking advantage of recent advances in areas like fibre and superfibre bundle theory, Krein spaces, gauge fields and groups, coherent states, etc., these principles can be consistently incorporated into a framework that can justifiably be said to provide the foundations for a quantum extrapolation of general relativity. This volume aims to present this approach in a way which places as much emphasis on fundamental physical ideas as on their precise mathematical implementation. References are also made to the ideas of Einstein, Bohr, Born, Dirac, Heisenberg and others, in order to set the work presented here in an appropriate historical context.

Theoretical Chemistry And Physics Of Heavy And Superheavy Elements

by U. Kaldor, Theoretical Chemistry And Physics Of Heavy And Superheavy Elements Books available in PDF, EPUB, Mobi Format. Download Theoretical Chemistry And Physics Of Heavy And Superheavy Elements books, Quantum mechanics provides the fundamental theoretical apparatus for describing the structure and properties of atoms and molecules in terms of the behaviour of their fundamental components, electrons and nudeL For heavy atoms and molecules containing them, the electrons can move at speeds which represent a substantial fraction of the speed of light, and thus relativity must be taken into account. Relativistic quantum mechanics therefore provides the basic formalism for calculating the properties of heavy-atom systems. The purpose of this book is to provide a detailed description of the application of relativistic quantum mechanics to the many-body prob lem in the theoretical chemistry and physics of heavy and superheavy elements. Recent years have witnessed a continued and growing interest in relativistic quantum chemical methods and the associated computa tional algorithms which facilitate their application. This interest is fu elled by the need to develop robust, yet efficient theoretical approaches, together with efficient algorithms, which can be applied to atoms in the lower part of the Periodic Table and, more particularly, molecules and molecular entities containing such atoms. Such relativistic theories and computational algorithms are an essential ingredient for the description of heavy element chemistry, becoming even more important in the case of superheavy elements. They are destined to become an indispensable tool in the quantum chemist's armoury. Indeed, since relativity influences the structure of every atom in the Periodic Table, relativistic molecular structure methods may replace in many applications the non-relativistic techniques widely used in contemporary research.

Relativistic Quantum Mechanics

by Armin Wachter, Relativistic Quantum Mechanics Books available in PDF, EPUB, Mobi Format. Download Relativistic Quantum Mechanics books, * Which problems do arise within relativistic enhancements of the Schrödinger theory, especially if one adheres to the usual one-particle interpretation? * To what extent can these problems be overcome? * What is the physical necessity of quantum field theories? In many textbooks, only insufficient answers to these fundamental questions are provided by treating the relativistic quantum mechanical one-particle concept very superficially and instead introducing field quantization as soon as possible. By contrast, this book emphasizes particularly this point of view (relativistic quantum mechanics in the ''narrow sense''): it extensively discusses the relativistic one-particle view and reveals its problems and limitations, therefore illustrating the necessity of quantized fields in a physically comprehensible way. The first two chapters contain a detailed presentation and comparison of the Klein-Gordon and Dirac theory, always with a view to the non-relativistic theory. In the third chapter, we consider relativistic scattering processes and develop the Feynman rules from propagator techniques. This is where the indispensability of quantum field theory reasoning becomes apparent and basic quantum field theory concepts are introduced. This textbook addresses undergraduate and graduate Physics students who are interested in a clearly arranged and structured presentation of relativistic quantum mechanics in the "narrow sense" and its connection to quantum field theories. Each section contains a short summary and exercises with solutions. A mathematical appendix rounds out this excellent textbook on relativistic quantum mechanics.

Non Relativistic Quantum Mechanics

by Ravinder R. Puri, Non Relativistic Quantum Mechanics Books available in PDF, EPUB, Mobi Format. Download Non Relativistic Quantum Mechanics books, This book develops and simplifies the concept of quantum mechanics based on the postulates of quantum mechanics. The text discusses the technique of disentangling the exponential of a sum of operators, closed under the operation of commutation, as the product of exponentials to simplify calculations of harmonic oscillator and angular momentum. Based on its singularity structure, the Schrödinger equation for various continuous potentials is solved in terms of the hypergeometric or the confluent hypergeometric functions. The forms of the potentials for which the one-dimensional Schrödinger equation is exactly solvable are derived in detail. The problem of identifying the states of two-level systems which have no classical analogy is addressed by going beyond Bell-like inequalities and separability. The measures of quantumness of mutual information in two two-level systems is also covered in detail.
