强盗？韦斯（RW）相变的虚化学势区域分析的Polyakov循环扩展Nambu？Jona-Lasinio（PNJL）模型在RW相变中，电荷共轭对称性被自发破缺，而扩展对称性（RW周期性）被保留。RW转变在端点处是二阶的。当化学势为零时，在二阶RW相变的终点处出现了一个交叉退禁闭相变，而电荷共轭对称性始终保持不变。
The Roberge?Weiss (RW) phase transition in the imaginary chemical potential region is analyzed by the Polyakov-loop extended Nambu?Jona-Lasinio (PNJL) model. In the RW phase transition, the charge-conjugation symmetry is spontaneously broken, while the extended symmetry (the RW periodicity) is preserved. The RW transition is of second order at the endpoint. At the zero chemical potential, a crossover deconfinement transition appears as a remnant of the second-order RW phase transition at the endpoint, while the charge-conjugation symmetry is always preserved.
