不可逆手征对称性与指数族

Non-Invertible Chiral Symmetry and Exponential Hierarchies

Clay Cordova, Kantaro Ohmori

摘要:

我们阐明了经典对称性遭受阿贝尔阿德勒贝尔Jackiw异常的命运。这些对称性并没有被完全破坏,而是以不可逆的拓扑全局对称缺陷的形式存在,其世界体积任意子的自由度通过分数霍尔效应中的磁单形全局对称性耦合到本体。这些不可逆的手征对称性意味着关联函数的选择规则,并出现在熟悉的无质量量子电动力学模型和轴子模型(以及它们的非阿贝尔推广)中。当动态磁单极子的传播破坏了相关联的体磁单形对称性时,非可逆手征对称性缺陷的选择规则被非微扰地违反。这就导致了轴子势和费米子质量在技术上自然的指数层次。

英文摘要:

We elucidate the fate of classical symmetries which suffer from abelian Adler-Bell-Jackiw anomalies. Instead of being completely destroyed, these symmetries survive as non-invertible topological global symmetry defects with worldvolume anyon degrees of freedom that couple to the bulk through a magnetic one-form global symmetry as in the fractional hall effect. These non-invertible chiral symmetries imply selection rules on correlation functions and arise in familiar models of massless quantum electrodynamics and models of axions (as well as their non-abelian generalizations). When the associated bulk magnetic one-form symmetry is broken by the propagation of dynamical magnetic monopoles, the selection rules of the non-invertible chiral symmetry defects are violated non-perturbatively. This leads to technically natural exponential hierarchies in axion potentials and fermion masses.
