Abstract

We study two-color QCD with two flavors of Wilson fermion as a function of quark chemical potential μ and temperature T , for two different lattice spacings and two different quark masses. We find that the quarkyonic region, where the behavior of the quark number density and the diquark condensate are described by a Fermi sphere of almost free quarks distorted by a Bardeen-Cooper-Schrieffer gap, extends to larger chemical potentials with decreasing lattice spacing or quark mass. In both cases, the quark number density also approaches its noninteracting value. The pressure at low temperature is found to approach the Stefan–Boltzmann limit from below.
