This book provides an introduction to the methods of coupled
quantum statistical field theory and Green's functions. The methods
of coupled quantum field theory have played a major role in the
extensive development of nonrelativistic quantum many-particle
theory and condensed matter physics. This introduction to the
subject is intended to facilitate delivery of the material in an
easily digestible form to advanced undergraduate physics majors at
a relatively early stage of their scientific development. The main
mechanism to accomplish this is the early introduction of
variational calculus and the Schwinger Action Principle,
accompanied by Green's functions. Important achievements of the
theory in condensed matter and quantum statistical physics are
reviewed in detail to help develop research capability. These
include the derivation of coupled field Green's function
equations-of-motion for a model electron-hole-phonon system,
extensive discussions of retarded, thermodynamic and nonequilibrium
Green's functions and their associated spectral representations and
approximation procedures. Phenomenology emerging in these
discussions include quantum plasma dynamic-nonlocal-screening,
plasmons, polaritons, linear electromagnetic response, excitons,
polarons, phonons, magnetic Landau quantization, van der Waals
interactions, chemisorption, etc. Considerable attention is also
given to low dimensional and nanostructured systems, including
quantum wells, wires, dots and superlattices, as well as materials
having exceptional conduction properties such as Superconductors,
Superfluids and Graphene.
