to do with real QCD? Certainly the nature of the high temperature transition at zero density depends strongly on the presence of dynamical quarks, as is becoming clear from large scale simulations of full QCD\[10\]. However, it is not a priori clear to us that a deconfinement transition or chiral symmetry restoration driven by high density should depend on the quarks moving, or whether the mere presence of the quarks would be enough. In particular, we had not expected to see the zero density first order transition disappear for very small quark densities, or for the signal of chiral symmetry restoration to vanish. This suggests that we might want to re-examine the conventional wisdom that a high density of quarks causes a phase transition similar to that caused by high temperature. This work was supported by DOE grant DF_,-FG03-95ER-40906.

N2 - We study lattice QCD in the limit that the quark mass and chemical potential are simultaneously made large, resulting in a controllable density of quarks which do not move. This is similar in spirit to the quenched approximation for zero density QCD. In this approximation we find that the deconfinement transition seen at zero density becomes a smooth crossover at any nonzero density, and that at low enough temperature chiral symmetry remains broken at all densities.
