Abstract

We study the effect of the change of the current quark mass on the inhomogeneous chiral phase in the QCD phase diagram and discuss the properties of the phase transition using the generalized Ginzburg-Landau expansion. The strong external magnetic field spreads this phase over the low chemical potential region even if the current quark mass is finite. This implies that the existence of this phase can be explored by the lattice QCD simulation.
