Description
We study the chemical potential dependence of the topological susceptibility with two-color two-flavor QCD. We find that at temperature , where Tc denotes the critical temperature at zero chemical potential, the topological susceptibility is almost constant until , while at , it decreases significantly from the value in a high regime. In this work, we perform the simulation for , which covers even the low temperature and the high chemical potential regime. In this regime, we introduce a diquark source term, which is characterized by , into the action. We also show our results for the phase diagram in a low temperature regime , which is obtained after taking the limit of physical observable.
