Induced Chern-Simons term in lattice QCD at finite temperature

Abstract

The general conditions for the Chern-Simons action to be induced as a nonuniversal contribution of fermionic determinant are formulated in the finite temperature lattice QCD. The dependence of the corresponding action coefficient on nonuniversal parameters (chemical potentials, vacuum features, etc. ) is explored. Special attention is paid to the role of $A_0$-condensate if it is available in this theory.
