论文摘要
Anyon模型是代数结构,它们在物质的拓扑阶段对通用拓扑特性进行了模拟,并且可以被视为在两个空间维度中拓扑顺序的数学表征。猜想的是,每个Anyon模型或数学上的模块化张量类别都可以实现为某些手性的保形场理论的表示类别,或者是数学上顶Vertex Operator代数/局部保形网络。对于为猜想提供支持的阿贝里亚人,该猜想是正确的。我们从几个不同的角度重新检查了Abelian Anyon Anyon模型。首先,ANYON模型是拓扑量子场理论和手性保形场理论的代数数据。虽然众所周知,每个Abelian Anyon模型都可以通过量子Abelian Chern-Simons理论和手性结合野外理论来实现,但构造不是算法。我们的目标是为Chern-Simons理论中的$ K $ -MATRIX提供这样的明确算法,即使是晶格保形场理论的积极明确的算法。其次,Anyon模型和手性保形场理论是物质拓扑阶段的宽大对应关系。但是,当考虑边缘理论和拓扑对称性的稳定性时,这种对应关系有有趣的微妙之处。因此,我们的重点是具有小额中央指控的极端性手性田间理论的算法重建。最终,我们猜测,对Abelian Anyon模型的重建更为强大:每个Abelian Anyon模型都可以被实现为某些非局部极端顶点操作员代数的表示类别,从而概括了琐碎的Anyon模型的月经实现。
Anyon models are algebraic structures that model universal topological properties in topological phases of matter and can be regarded as mathematical characterization of topological order in two spacial dimensions. It is conjectured that every anyon model, or mathematically unitary modular tensor category, can be realized as the representation category of some chiral conformal field theory, or mathematically vertex operator algebra/local conformal net. This conjecture is known to be true for abelian anyon models providing support for the conjecture. We reexamine abelian anyon models from several different angles. First anyon models are algebraic data for both topological quantum field theories and chiral conformal field theories. While it is known that each abelian anyon model can be realized by a quantum abelian Chern-Simons theory and chiral conformal field theory, the construction is not algorithmic. Our goal is to provide such an explicit algorithm for a $K$-matrix in Chern-Simons theory and a positive definite even one for a lattice conformal field theory. Secondly anyon models and chiral conformal field theories underlie the bulk-edge correspondence for topological phases of matter. But there are interesting subtleties in this correspondence when stability of the edge theory and topological symmetry are taken into consideration. Therefore, our focus is on the algorithmic reconstruction of extremal chiral conformal field theories with small central charges. Finally we conjecture that a much stronger reconstruction holds for abelian anyon models: every abelian anyon model can be realized as the representation category of some non-lattice extremal vertex operator algebra generalizing the moonshine realization of the trivial anyon model.
