Description

We study the chemical potential (μ) dependence of the topological susceptibility with two-color two-flavor QCD. We find that at temperature TTc/2, where Tc denotes the critical temperature at zero chemical potential, the topological susceptibility is almost constant until μ/mPS=1.6, while at TTc, it decreases significantly from the μ=0 value in a high μ regime. In this work, we perform the simulation for μ/T16, 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 j, into the action. We also show our results for the phase diagram in a low temperature regime (TTc/2), which is obtained after taking the j0 limit of physical observable.
