摘要:The 3-D Z(3) Potts model is a model for nite temperature QCD with heavy quarks. The chemical
potential in QCD becomes an external magnetic eld in the Potts model. Following Alford
et al.[3], we revisit this mapping, and determine the phase diagram for an arbitrary chemical potential,
real or imaginary. Analytic continuation of the phase transition line between real and
imaginary chemical potential can be tested with precision. Our results show that the chemical
potential weakens the heavy-quark deconnement transition in QCD.
