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

Dilepton Production as a Probe of Pion Condensation in Hot and Dense QCD Matter
Dilepton yields in isospin-asymmetric QCD matter exhibit low-mass enhancement and a plateau in the pion-condensed phase, distinguishing it from chirally broken or restored phases.
