具有奇异对称性的场论中的不可逆对偶界面

Non-Invertible Duality Interfaces in Field Theories with Exotic Symmetries

Ryan C. Spieler

AI总结:

本文在多种具有奇异对称性的场论模型中构造了不可逆对偶界面,分析其融合规则,发现其为高维规范奇异对称性的凝聚缺陷,并探讨了对紫外截断的依赖。

摘要:

近年来,全局对称性的概念已显著推广。这一推广的两个突出例子是支配分形子理论的奇异对称性以及不可逆对称性,后者不遵循群律进行融合。直到最近,这两者之间的相互作用才被研究。在本文中,我们在XY平板模型、XY立方体模型、具有全局偶极对称性的1+1维理论以及2+1维Lifshitz理论中提供了这种相互作用的进一步实例。它们类似于二维共形场论中的对偶对称性,其构造方法是首先在时空的一半上规范动量对称性的有限子群,然后进行对偶变换。我们分析了这些对称性的融合规则,发现它们是来自奇异对称性的高维规范类似物的凝聚缺陷。我们还讨论了它们在相关情况下对紫外截断的依赖性。

英文摘要:

In recent years, the concept of global symmetry has generalized considerably. Two dramatic examples of this generalization are the exotic symmetries that govern theories with fractons and non-invertible symmetries, which do not fuse according to a group law. Only recently has the interplay between these two been examined. In this paper, we provide further examples of the interplay in the XY plaquette model, XY cube model, 1+1 d theory with global dipole symmetry, and the 2+1 d Lifshitz theory. They are analogs of the duality symmetries in 2d CTFs and are constructed by first gauging a finite subgroup of the momentum symmetry on half of spacetime and then performing a duality transformation. We analyze the fusion rules of the symmetries and find that they are condensation defects from an analog of higher gauging exotic symmetries. We also address their dependence on the UV cutoff when relevant.
