摘要：

The phase structure of two-flavor QCD is explored for finite temperature T and finite baryon- and isospin-chemical potentials, mu(B) and mu(I), by using the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model. The PNJL model with the scalar-type eight-quark interaction can reproduce lattice QCD data in the mu(I)-T plane at mu(B)=0. In the mu(I)-mu(B)-T space, the critical endpoint of the chiral phase transition in the mu(B)-T plane at mu(I)=0 moves to the tricritical point of the pion-superfluidity phase transition in the mu(I)-T plane at mu(B)=0 as mu(I) increases.
