Single Superfield Representation for Mixed Retarded and Advanced Correlators in Disordered Systems

Disordered Systems and Neural Networks 2009-11-10 v2 Statistical Mechanics

Abstract

We propose a new single superfield representation for mixed retarded and advanced correlators for noninteracting disordered systems. The method is tested in the simpler context of Random Matrix theory, by comparing with well known universal behavior for level spacing correlations. Our method is general and could be especially interesting to study localization properties encoded in the mixed correlators of Quantum Hall systems.
