Popis: We study two-color QCD with two flavors of Wilson fermion as a function of quark chemical potential mu and temperature T. We find evidence of a superfluid phase at intermediate mu and low T where the quark number density and diquark condensate are both very well described by a Fermi sphere of nearly-free quarks disrupted by a BCS condensate. This gives way to a region of deconfined quark matter at higher T and mu, with the deconfinement temperature decreasing only very slowly with increasing chemical potential. We find that heavy quarkonium bound states persist in the S-wave channels at all T and mu, with an energy reflecting the phase structure. P-wave states appear not to survive in the quarkyonic region.
