While these systems strongly challenge the standard concepts and methods of the quantum many-body theory
, a new era is progressively unfolding, in which quantitative and detailed comparisons between theory and experiments is becoming possible in strong correlation regimes, even out of equilibrium.
The authors have organized the main body of their text in five chapters devoted to many-body theory
, topology and geometry, boundary conditions and self-adjoint extensions, and a wide variety of other related subjects.
He covers non-relativistic quantum mechanics, thermal and statistical physics, many-body theory
, classical field theory and relativity, and relativistic quantum mechanics and gauge theories.
What Wen (physics, Massachusetts Institute of Technology) presents is an alternative paradigm to basic ideas and models in applying many-body theory
to condensed-matter physics that relate to understanding of the origin of light and other phenomena.
of molecules, clusters, and condensed phases.
