标题： 3D TFTs from 4d ${\cal N}=2$ BPS Particles

摘要： 我们提出一种通用策略，以构建具有四个超电荷的三维规范理论，这些理论在红外区域享有超对称增强。 这些结果的红外 SCFT 具有特别良好性质的拓扑扭曲，以及边界有理张量代数，使得相关的模张量范畴由拓扑扭曲控制。 这些理论来源于四维阿格里尔斯-道格拉斯型理论的扭曲圆周紧致化。 我们开发了一种新算法来计算或操作与这些理论相关的受保护量，例如椭球分区函数和超共形指标以及半指标。 显示英文摘要

摘要： We propose a general strategy to build three-dimensional gauge theories with four supercharges which enjoy a supersymmetry enhancement in the IR. The resulting IR SCFTs admit topological twists with particularly nice properties, as well as boundary rational chiral algebras such that the associated Modular Tensor Categories are controlled by the topological twist. The theories arise from a twisted circle compactification of four-dimensional theories of Argyres-Douglas type. We develop a novel algorithm to compute or manipulate protected quantities associated to these theories, such as ellipsoid partition functions and superconformal indices and half-indices.
