The Physics of Quantum Fields. Cet article n’est pas disponible.The Physics of Quantum Fields

This book provides a general introduction to the physics of quantized fields and many-body physics. It is intended for students with interests ranging from particle and nuclear theory through quantum optics to condensed-matter physics. The discussion emphasizes the physical and visualizable aspects of the subject and concentrates on the basic conceptual issues that many students find difficult. Many of the examples are drawn from condensed matter physics.

A gentle introduction to the physics of quantized fields and many-body physics. Based on courses taught at the University of Illinois, it concentrates on the basic conceptual issues that many students find difficult, and emphasizes the physical and visualizable aspects of the subject. While the text is intended for students with a wide range of interests, many of the examples are drawn from condensed matter physics because of the tangible character of such systems. The first part of the book uses the Hamiltonian operator language of traditional quantum mechanics to treat simple field theories and related topics, while the Feynman path integral is introduced in the second half where it is seen as indispensable for understanding the connection between renormalization and critical as well as non-perturbative phenomena.
