Description
At nonzero isospin chemical potential, in addition to the usual hadronic and quark-gluon plasma phases, a pion condensed phase appears in the QCD phase diagram, bounded by a second-order transition line. This setup is sign-problem-free and can be studied using standard lattice Monte-Carlo methods. An overview of the phase diagram and the possible applications of finite isospin simulation results is given. Moreover, to approach the chiral limit of the phase diagram, we compare the behavior of the pion condensation line at the physical and half physical light quark masses showing how the pion condensation line moves as the light quark mass goes to zero.
