标题： The 3-state Potts model as a heavy quark finite density laboratory

摘要： 三维Z(3)Potts模型是用于研究带有重夸克的有限温度QCD的模型。 QCD中的化学势在Potts模型中成为外部磁场。 遵循Alford等人。 \cite{Alford_et_al}，我们重新审视这种映射，并确定任意化学势（实数或虚数）下的相图。 实数和虚数化学势之间相变线的解析延拓可以精确测试。 我们的结果表明，化学势会削弱QCD中重夸克的禁闭转变。 显示英文摘要

摘要： The 3-D Z(3) Potts model is a model for finite temperature QCD with heavy quarks. The chemical potential in QCD becomes an external magnetic field in the Potts model. Following Alford et al.\cite{Alford_et_al}, 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 deconfinement transition in QCD.
