QCD topology and axion properties in an isotropic hot and dense medium

Abstract We study the QCD topology and axion properties at finite temperature and chemical potential in the framework of the two-flavor Nambu–Jona-Lasinio model. We find that the behaviors of the two lowest cumulants of the QCD topological charge distribution and axion properties are highly sensitiv...
