Many-Body Methods for Atoms, Molecules and Clusters [E-Book] / by Jochen Schirmer.
This book provides an introduction to many-body methods for applications in quantum chemistry. These methods, originating in field-theory, offer an alternative to conventional quantum-chemical approaches to the treatment of the many-electron problem in molecules. Starting with a general introduction...
