2+1维量子场论中的奇异对称性、对偶性和分形

Exotic Symmetries, Duality, and Fractons in 2+1-Dimensional Quantum Field Theory

Nathan Seiberg, Shu-Heng Shao

摘要:

本文讨论2+1维非标准连续量子场论。他们表现出异国情调的全球对称性,一个微妙的频谱充电激发,和对偶类似的对偶系统在1+1维。这些连续模型代表了某些已知晶格系统的低能极限。这些连续场论的一个关键方面是不连续场结构所起的重要作用。在两篇配套论文中,我们将介绍这些系统的3+1维版本。特别地,我们将讨论一些模型的分形子的连续量子场论。

英文摘要:

We discuss nonstandard continuum quantum field theories in 2+1 dimensions. They exhibit exotic global symmetries, a subtle spectrum of charged excitations, and dualities similar to dualities of systems in 1+1 dimensions. These continuum models represent the low-energy limits of certain known lattice systems. One key aspect of these continuum field theories is the important role played by discontinuous field configurations. In two companion papers, we will present 3+1-dimensional versions of these systems. In particular, we will discuss continuum quantum field theories of some models of fractons.
