论文摘要
我们讨论2+1维中的非标准连续量子场理论。它们表现出异国情调的全局对称性，微妙的带电激发频谱以及类似于1+1个维度二元性的二元性。这些连续模型代表了某些已知晶格系统的低能限制。这些连续性字段理论的一个关键方面是不连续的字段配置所扮演的重要作用。在两篇同伴论文中，我们将介绍这些系统的3+1维版本。特别是，我们将讨论某些模型的连续量子场理论。
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.
