Die berühmte Vorlesung von Freeman Dyson - nun erstmals auf Deutsch. In den 1940er Jahren zeigte Freeman Dyson die Äquivalenz zwischen den beiden Formulierungen der QED - des Pfadintegralansatzes von Richard Feynman und der Variationsmethoden von Julian Schwinger - und bewies somit die Konsistenz der QED. Dieses Buch beinhaltet die wertvollen - nie zuvor auf Deutsch publizierten - Vorlesungen über Quantenfeldtheorie, die Dyson an der Cornell Universität 1951 gehalten hat. Der Theoretiker Edwin Thompson Jaynes bemerkte dazu: "Für eine Generation von Physikern waren diese Vorlesungen ein Gewinn: klarer und besser motiviert als Feynmans Vorlesungen, und schneller und kompakter als Schwingers." Zukünftige Leser werden diese Vorlesungen ebenfalls mit großem Genuss lesen und von dem klaren Stil profitieren, der für Dyson stets so charakteristisch gewesen ist. Aus dem Inhaltsverzeichnis: 1 - Die Diracgleichung, 2 - Streuprobleme und die Born-Approximation, 3 - Die klassische und quantenmechanische Feldtheorie, 4 - Beispiele quantisierter Feldtheorien (Maxwellfeld, Diracelektronen), 5 - Streuprobleme freier Teilchen (Paar Annihilation, Möller-Streuung, Klein-Nishina-Formel), 6 - Allgemeine Theorie der Streuung (Feynman-Graphen, Infrarotkatastrophe), 7 - Streuung an einem statischen Potenzial und experimentelle Ergebnisse.

Written by a renowned professor of physics, this introductory text is geared toward graduate students taking a year-long course in quantum mechanics in which the third quarter is devoted to relativistic wave equations and field theory. Difficult concepts are introduced gradually, and the theory is applied to physically interesting problems. After an introductory chapter on the formation of quantum mechanics, the treatment advances to examinations of the quantum theory of the free electromagnetic field, the interaction of radiation and matter, second quantization, the interaction of quantized fields, and quantum electrodynamics. Additional topics include the theory of beta decay, particles that interact among themselves, quasi particles in plasmas and metals, and the problem of infinities in quantum electrodynamics. The Appendix contains selected answers to problems that appear throughout the text.

Quantum field theory is the application of quantum mechanics to systems with infinitely many degrees of freedom. This 2007 textbook presents quantum field theoretical applications to systems out of equilibrium. It introduces the real-time approach to non-equilibrium statistical mechanics and the quantum field theory of non-equilibrium states in general. It offers two ways of learning how to study non-equilibrium states of many-body systems: the mathematical canonical way and an easy intuitive way using Feynman diagrams. The latter provides an easy introduction to the powerful functional methods of field theory, and the use of Feynman diagrams to study classical stochastic dynamics is considered in detail. The developed real-time technique is applied to study numerous phenomena in many-body systems. Complete with numerous exercises to aid self-study, this textbook is suitable for graduate students in statistical mechanics and condensed matter physics.

This text concerns continuum mechanics, electrodynamics and the mechanics of electrically polarized media, and gravity. Geared toward advanced undergraduates and graduate students, it offers an accessible approach that formulates theories according to the principle of least action. The chief advantage of this formulation is its simplicity and ease, making the physical content of classical subjects available to students of physics in a concise form. Author Davison E. Soper, a Professor of Physics at the University of Oregon, intended this treatment as a primary text for courses in classical field theory as well as a supplement for courses in classical mechanics or classical electrodynamics. Topics include fields and transformation laws, the principle of stationary action, general features of classical field theory, the mechanics of fluids and elastic solids, special types of solids, nonrelativistic approximations, and the electromagnetic field. Additional subjects include electromagnetically polarized materials, gravity, momentum conservation in general relativity, and dissipative processes.
