موضوعات در مکانیک کوانتومی پیشرفته

This graduate-level text is based on a course in advanced quantum mechanics, taught many times at the University of Massachusetts, Amherst. Topics include propagator methods, scattering theory, charged particle interactions, alternate approximate methods, and Klein-Gordon and Dirac equations. Problems appear in the flow of the discussion, rather than at the end of chapters. 1992 edition I. Propagator Methods -- 1. Basic Quantum Mechanics -- 2. The Propagator -- 3.
