Article overview

Nonlinear sigma model approach for chiral fluctuations and symmetry breakdown in Nambu-Jona-Lasinio model
Egor Babaev ;
Date:	10 Jun 2000
Journal:	Phys.Rev. D62 (2000) 074020
Subject:	hep-ph cond-mat hep-th
Abstract:	In this paper we discuss symmetry breakdown in NJL model at low N_c. In particular we propose a modified NJL model that displays a symmetry breakdown and also at finite temperatures under certain conditions the chiral fluctuations in this model give rise to a phase analogous to pseudogap phase of strong-coupling and low carrier density superconductors.
