Abstract
In the frame of flavor SU(2) Nambu-Jona-Lasinio model with UA(1) breaking term we found that, the structure of two chiral phase transition lines does not exist at low isospin density, and the critical isospin chemical potential for pion superfluidity is exactly the pion mass in the vacuum.
