Scattering of Photons by Many-Electron Systems by Alexey N. Hopersky , Victor A. Yavna
English | PDF | 2010 | 145 Pages | ISBN : 3642042554 | 4.4 MB

This book deals with quantum physical calculations of anomalous scattering of photons by bound electrons. The main attention is paid to studies of the process of photon scattering in the energy range of deep levels of such many-electron systems as atoms, atomic ions and simple molecules. The book is written for scientists and graduate students, working in the field of atomic and molecular spectroscopy, physics of plasmas, lasers, solid state, ionizing radiation and astrophysics. It can also be used as additional textbook for a special topic of quantum mechanics.

Relativistic Quantum Mechanics

Relativistic Quantum Mechanics by Hartmut M. Pilkuhn
English | PDF (True) | 2003 | 244 Pages | ISBN : N/A | 19.2 MB

In this book, quantum mechanics is developed from the outset on a relativistic basis, using the superposition principle, Lorentz invariance and gauge invariance. Nonrelativistic quantum mechanics as well as classical relativistic mechanics appear as special cases. They are the sources of familiar names such as "orbital angular momentum", "spin-orbit coupling" and "magnetic moment" for operators of the relativistic quantum formalism. The theory of binaries, in terms of differential equations, is treated for the first time in this book. These have the mathematical structure of the corresponding one-body equations (Klein–Gordon for two spinless particles, Dirac for two spinor particles) with a relativistically reduced mass. They allow the calculation of radiative corrections via the vector potential operator.

Quantum Mathematical Physics: Atoms, Molecules and Large Systems

Quantum Mathematical Physics: Atoms, Molecules and Large Systems by Walter Thirring
English | PDF | 2002 | 599 Pages | ISBN : 3540430784 | 40.5 MB

This edition combines the earlier two volumes on Quantum Mechanics of Atoms and Molecules and on Quantum Mechanics of Large Systems, thus including in a single volume the material for a two-semester course on quantum physics. Since this volume is already quite heavy, I could not include many new results which show how lively the subject is. I just want to mention that inequality (IV:4. 1. l. 1) has been sharpened by T. Weidl by a factor 2][ and the difficult problem 1 of (III:4. 6) has been solved by A. Martin. I have to thank N. Ilieva for the devotion in preparing this new edition. Vienna, November 2001 Walter Thirring Preface to the Second Edition: Quantum Mechanics of Atoms and Molecules Ever since the first edition of this volume appeared in 1980 quantum statistical mechanics has florished. Innumerable results in many areas have been obtained and it would require a series of volumes to do justice to all of them. On the other hand the first edition was already rather crowded with many details so it would not be overburdened any more. Thus I added only one chapter on quantum ergodic theory where one can get the main notions across without too much pain. Nevertheless many subjects treated in the book had splendidely developed ever since and the only way out I could see is to add some recent references which the interested reader can consult.

Gauge Theory of Weak Interactions, Third Edition

Gauge Theory of Weak Interactions, Third Edition by Walter Greiner , Berndt Müller
English | PDF | 2000 | 413 Pages | ISBN : 3540676724 | 30.3 MB

Gauge Theory of Weak Interactions treats the unification of electromagnetic and weak interactions and considers related phenomena. First, the Fermi theory of beta decay is presented, followed by a discussion of parity violation, clarifying the importance of symmetries. Then the concept of a spontaneously broken gauge theory is introduced, and all necessary mathematical tools are carefully developed. The "standard model" of unified electroweak interactions is thoroughly discussed including current developments. The final chapter contains an introduction to unified theories of strong and electroweak interactions. Numerous solved examples and problems make this volume uniquely suited as a text for an advanced course. This third edition has been carefully revised.

The fundamental goal of physics is an understanding of the forces of nature in their simplest and most general terms. Yet there is much more involved than just a basic set of equations which eventually has to be solved when applied to specific problems. We have learned in recent years that the structure of the ground state of field theories (with which we are generally concerned) plays an equally funda­ mental role as the equations of motion themselves. Heisenberg was probably the first to recognize that the ground state, the vacuum, could acquire certain prop­ erties (quantum numbers) when he devised a theory of ferromagnetism. Since then, many more such examples are known in solid state physics, e. g. supercon­ ductivity, superfluidity, in fact all problems concerned with phase transitions of many-body systems, which are often summarized under the name synergetics. Inspired by the experimental observation that also fundamental symmetries, such as parity or chiral symmetry, may be violated in nature, it has become wide­ ly accepted that the same field theory may be based on different vacua. Practical­ ly all these different field phases have the status of more or less hypothetical models, not (yet) directly accessible to experiments. There is one magnificent ex­ ception and this is the change of the ground state (vacuum) of the electron-posi­ tron field in superstrong electric fields.

On the Wave Nature of Matter: A New Approach to Reconciling Quantum Mechanics and Relativity

On the Wave Nature of Matter: A New Approach to Reconciling Quantum Mechanics and Relativity by Donald C. Chang
English | PDF EPUB (True) | 2024 | 341 Pages | ISBN : 3031487761 | 41.1 MB

This book presents a new approach to understanding the foundation of quantum physics through the "quantum wave model" hypothesis. It addresses some of the key challenges in the current quantum theory, including the conflict between quantum mechanics and relativity, and offers a comprehensive solution to many of the existing mysteries in the field. By proposing that the vacuum is a dielectric medium and quantum particles are quantized excitation waves of the vacuum, the book provides a clear physical interpretation of wave-particle duality and explains the physical basis of energy, momentum, and mass.

Quantum Field Theory: Competitive Models by Bertfried Fauser, Jürgen Tolksdorf, Eberhard Zeidler
English | PDF (True) | 2009 | 448 Pages | ISBN : 3764387351 | 3.4 MB

For more than 70 years, quantum field theory (QFT) can be seen as a driving force in the development of theoretical physics. Equally fascinating is the fruitful impact which QFT had in rather remote areas of mathematics. The present book features some of the different approaches, different physically viewpoints and techniques used to make the notion of quantum field theory more precise. For example, the present book contains a discussion including general considerations, stochastic methods, deformation theory and the holographic AdS/CFT correspondence. It also contains a discussion of more recent developments like the use of category theory and topos theoretic methods to describe QFT. The present volume emerged from the 3rd 'Blaubeuren Workshop: Recent Developments in Quantum Field Theory', held in July 2007 at the Max Planck Institute of Mathematics in the Sciences in Leipzig/Germany. All of the contributions are committed to the idea of this workshop series: 'To bring together outstanding experts working in the field of mathematics and physics to discuss in an open atmosphere the fundamental questions at the frontier of theoretical physics'.

Classical Nonintegrability, Quantum Chaos

Classical Nonintegrability, Quantum Chaos by Andreas Knauf , Yakov G. Sinai , Viviane Baladi
English | PDF | 1997 | 104 Pages | ISBN : 3764357088 | 7.6 MB

Our DMV Seminar on 'Classical Nonintegrability, Quantum Chaos' intended to introduce students and beginning researchers to the techniques applied in nonin­ tegrable classical and quantum dynamics. Several of these lectures are collected in this volume. The basic phenomenon of nonlinear dynamics is mixing in phase space, lead­ ing to a positive dynamical entropy and a loss of information about the initial state. The nonlinear motion in phase space gives rise to a linear action on phase space functions which in the case of iterated maps is given by a so-called transfer operator. Good mixing rates lead to a spectral gap for this operator.

Multiscale Methods in Quantum Mechanics: Theory and Experiment

Multiscale Methods in Quantum Mechanics: Theory and Experiment by Philippe Blanchard, Gianfausto Dell’Antonio
English | PDF | 2004 | 223 Pages | ISBN : 0817632565 | 21 MB

In the last few years, multiscale methods have lead to spectacular progress in our understanding of complex physical systems and have stimulated the development of very refined mathematical techniques. At the same time on the experimental side, equally spectacular progress has been made in developing experimental machinery and techniques to test the foundations of quantum mechanics. In view of this progress, this volume is very timely; it is the first text totally devoted to multiscale methods as applied to various areas of physics and to the relative developments in mathematics.

Prestigious Discoveries at CERN: 1973 Neutral Currents 1983 W & Z Bosons by Roger Cashmore, Luciano Maiani (CERN Director General), Jean-Pierre Revol
English | PDF | 2003 | 201 Pages | ISBN : 3540207503 | 8.7 MB

The discoveries of neutral currents and of the W and Z bosons marked a watershed in the history of CERN. They established the validity of the electroweak theory and convinced physicists of the importance of renormalizable non-Abelian gauge theories of fundamental interactions. The articles collected in this book have been written by distinguished physicists who contributed in a crucial way to these developments. The book provides a historical account of those discoveries and of the construction and testing of the Standard Model. It also contains a discussion of the future of particle physics and gives an updated status of the LHC and its detectors currently being built at CERN. The book addresses those readers interested in particle physics including the educated public.
