Self-consistent Quantum-Field Theory and Bosonization for Strongly Correlated Electron Systems

Mehr zum Buch

Advanced quantum field theoretical techniques for many-particle systems are explored in this research monograph, focusing on methods that extend beyond perturbation theory. It details various resummation schemes for Feynman diagrams, providing approximations particularly effective for strongly correlated fermion and boson systems. The work serves as a valuable resource for researchers seeking to deepen their understanding of complex interactions in quantum systems.
