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.

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.

An up-to-date account of this cutting-edge research in a consistent and understandable framework, of special interest to experts in other areas of electronic structure and/or quantum

many-body theory.

Many-body theory of molecules, clusters, and condensed phases.
