Self-consistent Quantum-Field Theory and Bosonization for Strongly Correlated Electron Systems by Rudolf Haussmann
English | PDF | 1999 | 181 Pages | ISBN : 3540658122 | 15.3 MB
This research monograph offers an introduction to advanced quantum field theoretical techniques for many-particle systems beyond perturbation theory. Several schemes for resummation of the Feynman diagrams are described. The resulting approximations are especially well suited for strongly correlated fermion and boson systems.
