轴向异常和嵌套阐明的上下文中的不均匀的手征相。利用1+ 1维Gross-Neveu模型，从两个不同的角度讨论轴反常和嵌套：一个是非均匀手征跃迁，另一个是超导中的Fulde-Ferrel-Larkin-Ovchinnikov（FFLO）态，它们通过对偶性的方式密切相关。结果表明，轴异常导致一种特殊的FFLO状态的二维Nambu-JonaLasinio模型中，轴异常表现在不同的模式。嵌套是这两种现象的驱动机制，但其实现具有不同的特征。我们重新考虑在二元性的背景下嵌套的效果。
Axial anomaly and nesting is elucidated in the context of the inhomogeneous chiral phase. Using the Gross-Neveu models in 1+ 1 dimensions, we shall discuss axial anomaly and nesting from two different points of view: one is inhomogeneous chiral transition and the other is the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state in superconductivity, which are closely related to each other by way of duality. It is shown that axial anomaly leads to a particular kind of the FFLO state within the two dimensional Nambu-Jona Lasinio model, where axial anomaly is manifested in a different mode. Nesting is a driving mechanism for both phenomena, but its realization has different features. We reconsider the effect of nesting in the context of duality.
