A guide to Feynman diagrams in the many-body problem
Richard D. Mattuck
Superb introduction for non-specialists to important area of modern physics. Major concepts—Feynman diagrams, quasi particles, Fermi systems at finite temperature, superconductivity, vacuum amplitude, more. Also Dyson’s equation, ladder approximation, much else. Exercises. Second (1974) edition. "...a great delight to read."—Physics Today.
