Jose J. Fernandez-Melgarejo, Giacomo Giorgi, Diego Marques, J. A. Rosabal

AI总结:

本文在IIB型超引力中构造了与0-、2-、4-和6-形式对称性相关的非可逆拓扑算符,通过引入分数荷并保持规范不变性,揭示了类似分数量子霍尔效应的新型对称性及其SymTFT。

摘要:

在这项工作中,我们揭示了一组与IIB型超弦有效理论相关的0-、2-、4-和6-形式对称性相联系的非可逆拓扑算符。通过确定与这些对称性相对应的$\text{SL}(2,\mathbb{Z})$-协变守恒流,我们首先推导出一组$\text{SL}(2,\mathbb{Z})$不变的、可逆的拓扑算符,这些算符囊括了该理论中固有的整数BPS荷。进一步地,通过在保持规范不变性的同时纳入分数荷,我们为每种广义对称性引入了非可逆拓扑算符,特别是针对$\text{SL}(2,\mathbb{Z})$ 0-形式对称性。我们将它们识别为一种类似于分数量子霍尔效应(FQHE)的非可逆算符的新型对称性,并研究了它们对带电物体的作用以及通过半(高阶)规范化得到的相关SymTFT。

英文摘要:

In this work, we uncover a collection of non invertible topological operators linked to the 0-, 2-, 4- and 6-form symmetries related to the type IIB superstring effective theory. By pinpointing the $\text{SL}(2,\mathbb{Z})$-covariant conserved currents corresponding to these symmetries, we first derive a set of $\text{SL}(2,\mathbb{Z})$ invariant invertible topological operators that encapsulate the integer BPS charges inherent to the theory. Moving forward, by incorporating fractional charges while maintaining gauge invariance, we introduce the non invertible topological operators for each generalized symmetry, and in particular for the $\text{SL}(2,\mathbb{Z})$ 0-form symmetry. Identifying them as a novel kind of symmetries reminiscent of fractional quantum Hall effect (FQHE)-like non invertible operators, we study their action on charged objects and their associated SymTFTs obtained via half (higher) gauging.
