Project management at the University of Würzburg:

Participating scientists:

Abstract:
analysis of charge gaps and their critical properties, comparing Coulomb- and spin glass pseudogaps; numerical analysis of quantum dynamic displacements of the quantum critical point of metallic spin glass-paramagnet transitions. Search for exact T=0 solutions of all SK models on spin and on fermionic space. New weak hopping expansions around the insulating solutions of spin glass phases. Comparison of frustration effects in clean - and in disordered fermionic systems. Competition between spin glass and special superconducting phases

Key words:
    quantum critical points
    dynamic effects
    new weak hopping expansions
