Quantum Leaps and Bounds: Quantum Mechanics in Fock Space
by
Malcolm
McMillan, Department of Physics, University of British Columbia
Quantum Leaps and Bounds (QLB) is the six-volume set of lecture notes in
book form for
Physics 500, the introductory graduate quantum mechanics course given by
Malcolm McMillan at UBC at various times since 1973.
This volume of QLB gives an introduction to the second-quantization
description of nonrelativistic many-body systems. The table of contents of
this volume is:
