Many-Body Theory Exposed! Propagator Description of Quantum Mechanics in Many-Body Systems (2nd Edition)

Presents a unified treatment of many different many-body systems using the approach of self-consistent Green's functions. This book includes the description of atomic Bose-Einstein condensates. It covers elementary concepts like second quantization and mean-field properties.
