本文根据Goldstone定理讨论了有限温度下手征交叉的正确定义。与通常使用的手征凝聚体的最大变化不同，我们提出用赝Goldstone玻色子的Mott跃迁来定义交叉温度，从定义上保证了Goldstone定理。我们分析和数值证明了这一属性的Pauli-Villars正则化NJL模型的框架。在外加磁场中，我们发现Mott转变温度表现出逆磁催化效应。
We discuss the proper definition for the chiral crossover at finite temperature, based on the Goldstone's theorem. Different from the usually used maximum change of chiral condensate, we propose to define the crossover temperature by the Mott transition of pseudo-Goldstone bosons, which, by definition, guarantees the Goldstone's theorem. We analytically and numerically demonstrate this property in frame of a Pauli-Villars regularized NJL model. In external magnetic field, we find that the Mott transition temperature shows an inverse magnetic catalysis effect.
