Aspects of Symmetry : Selected Erice Lectures

Rating:
Summary: A Classic
Review: Coleman is one of the best field theorists and a great lecturer. His style in both research and lectures can be summarized as "turning obvious into trivial". Every topic is presented in the simplest possible way without loss of deep insights, which makes the book extremely comprehensible. The chapter on instantons is absolutely classic.

Summary: unconventional QFT book
Review: Many physicists say that Coleman is one of the great field theoriest in time. This is the collection of what he had lectured. Each chapter has own its importance. The advantage of the book is that he avoided the mathematical complication to explain the real physics. It is very unique feature in the QFT books. So you can get the concept of field theory without mathematical jargon which most students hate.

Summary: A wonderful book to supplement one's QFT knowledge
Review: This 400-page book contains eight lectures of varying length (some are quite long). The first two are not very useful, but the remainder of the book is wonderful. It covers topics like scale invariance, Callan-Symanzik (RG) equations, renormalization theory (Hepp's theorem), spontaneously broken symmetries, classical and quantum solitons, instantons (in QM and in gauge theories), and 1/N expansion. These are all useful topics and must be understood by those in the field, and yet not all of them are covered by ordinary quantum field theory books like Peskin & Schroeder. The style is very friendly and readable and includes a lot of endnotes, appendices, and references. This book does not "read" like Peskin/Schroeder or Weinberg or Itzykson/Zuber; those books don't read. This one does. The equations are easy to follow and this book showcases the strength of Coleman's pedagogical style. In fact I can vouch that the tone and content of these lectures serves as a close substitue for Coleman's lectures themselves. The topics were all basically developed in the 1970s, and were themselves all quite hot research areas before supersymmetry and string theory revolutionized high-energy physics. However, the majority of this book is not an anachronism -- the renormalization group, spontaneously broken symmetries, solitons, instantons, and 1/N expansion all pervade modern physics.
