The main part of this book is devoted to the simplest kind of Green's functions, namely the solutions of linear differential equations with a -function source. It is shown that these familiar Green's functions are a powerful tool for obtaining relatively simple and general solutions of basic problems such as scattering and boundlevel information. The bound-level treatment gives a clear physical understanding of "difficult" questions such as superconductivity, the Kondo effect, and, to a lesser degree, disorder-induced localization. The more advanced subject of many-body Green's functions is presented in the last part of the book.

At what level of physical existence does "quantum behavior" begin? How does it develop from classical mechanics? This book addresses these questions and thereby sheds light on fundamental conceptual problems of quantum mechanics. Quantum-Classical Correspondence elucidates the problem by developing a procedure for quantizing stochastic systems (e.g. Brownian systems) described by Fokker-Planck equations. The logical consistency of the scheme is then verified by taking the classical limit of the equations of motion and corresponding physical quantities. Perhaps equally important, conceptual problems concerning the relationship between classical and quantum physics are identified and discussed. Physical scientists will find this an accessible entrée to an intriguing and thorny issue at the core of modern physics.

This second edition of Exercises in Quantum Mechanics has been much revised, updated and enlarged in order to cater more comprehensively for the growing need of students of quantum mechanics to have a better insight and grasp of this fascinating but mathematically convoluted branch of physics. The number of illustrative problems solved has been increased from 114 to 228, and new exercises have been added to each of the chapters. The problems discussed have been carefully chosen so as to involve a minimum of technical complexity whilst emphasising the consequences of the quantum-mechanical formalism. Various chapters have been extended significantly and three new chapters are included to make this volume more complete and sophisticated in its coverage of elementary quantum mechanics, principally by including material dealing with angular momentum coupling and tensor algebra. The presentation of the material has also been made much more attractive. This revised edition will be especially useful to advanced undergraduate and graduate students of quantum mechanics and to all teachers of this subject.

The enormous advances in observational techniques over the last two decades has produced a wealth of data and unexpected discoveries which have helped to reshape astrophysics as a field with well-formulated theories and sophisticated numerical calculations. In nuclear particle physics, plasma physics, as well as in general relativity, the Universe has become a laboratory for cutting-edge research. The courses collected in the book are intended to provide students with this insight, giving a general background on each topic such as cosmic rays, nuclear and neutrino astrophysics, solar physics and strong fields, as well as a presentation of the current research and open problems. The book is aimed at graduate students in physics and astrophysics, as well as researchers, bridging a gap between the specialized reviews and the comprehensive books.
