【簡介】 The book is based on a one-semester lecture course that the author taught at Charles University for more than ten years, as a follow-up to an introductory basic course. Its contents corresponds to an intermediate level of quantum field theory, and includes topics like regularization and renormalization methods, Cutkosky rules for imaginary part of loop diagrams, infrared divergences in quantum electrodynamics, renormalization group techniques, basics of quantum chromodynamics including the connection between unitarity and ghosts, asymptotic freedom, ABJ axial anomaly and trace anomaly.This book is aimed at any reader who has mastered techniques for evaluation of Feynman diagrams in field theory models up to the one-loop level. The accent is on detailed explicit calculations of tree-level and one-loop Feynman diagrams in quantum electrodynamics and quantum chromodynamics. In particular, the chapters devoted to the ABJ anomaly cover both its ultraviolet and infrared aspects, and display computational details in an extent not quite common in other competing texts available in current literature.

【簡介】 Accelerators, as research and industrial tools, are increasingly becoming a key driver of the advances of a modern society. As accelerators and our understanding of its science evolve to meet the ever-increasing needs of society, the field of accelerator physics has advanced and deepened over the past few decades, with many of its branches developing into special topics of research by their own rights. It is appropriate, at this time, to start accumulating this hard-earned expertise by the accelerator physics community. With this view, a selection of these special topics is presented in this volume; Special Topics in Accelerator Physics. Although not exhaustive, these special topics are chosen to present accelerator physics as a diversified and exciting field, and is written based on the practicing and teaching experiences the author has accumulated over the past decades. Presented as a textbook, the material on each topic is intended to be self-contained. The reader is assumed to have a basic knowledge of accelerator physics to put the material in some context.

Quantum mechanics is one of the most successful theories in science, and is relevant to nearly all modern topics of scientific research. This textbook moves beyond the introductory and intermediate principles of quantum mechanics frequently covered in undergraduate and graduate courses, presenting in-depth coverage of many more exciting and advanced topics. The author provides a clearly structured text for advanced students, graduates and researchers looking to deepen their knowledge of theoretical quantum mechanics. The book opens with a brief introduction covering key concepts and mathematical tools, followed by a detailed description of the Wentzel–Kramers–Brillouin (WKB) method. Two alternative formulations of quantum mechanics are then presented: Wigner's phase space formulation and Feynman's path integral formulation. The text concludes with a chapter examining metastable states and resonances. Step-by-step derivations, worked examples and physical applications are included throughout. Covers many advanced mathematical techniques in quantum mechanics, each illustrated with detailed examples Presents two alternative formulations of quantum mechanics; the path integral and phase space formulations, which are useful in advanced applications Provides a pedagogical and thorough overview of the exact WKB method, which plays an increasingly important role in many areas of modern physics
