Statistical complexity in an SU(2) × SU(2) many-fermion environment

Abstract

We consider a typical many body problem. In particular, we study an exactly solvable fermion system. We apply to it recently developed statistical quantifiers like the statistical complexity C and the disequilibrium D. The idea consists in trying to ascertain whether statistical quantifiers are able to describe purely dynamic many-body features. Some revealing insights are obtained, specially in what refers to phase transitions.
