Abstract:
In the chiral symmetry breaking phase described by the NJL model at quark level, along with the chiral symmetry restoration the ratio of shear viscosity to entropy density η/s drops down monotonously and reaches the minimum at the critical point, while the ratio of
bulk viscosity to entropy density ζ/s behaves oppositely.
