Electron Correlations in Molecules and Solids

Quantum chemistry and solid-state theory are two important
related fields ofresearch that have grown up with almost no
cross communication. This book   brdges the gap between the
two. In the first half, new concepts for treatingweak and
strong correlations are developed, and standard                              quantum
chemical methods as well as denisty functional integral,                  and
Monte Carlo methods are discussed. The second half                                 discusses
applications of the theory to molecules,                                       semiconductors,
homogeneous metallic systems, transition metals,                  and
strongly correlated systems such as heavy-fermion systems
and the   new high-T superconducting materials.
