标题： G/G models as the strong coupling limit of topologically massive gauge theory

摘要： 我们证明，在拓扑质量规范理论的强耦合极限中计算规范不变算符的真空期望值的问题等价于在$G_k/G$模型中计算类似算符的问题，其中$k$是 Chern-Simons 项的整数系数。 $G_k/G$模型是一个拓扑场论，许多关联函数可以解析地计算。 我们还证明，在有限温度下强耦合理论的 Polyakov 环算符和规范场的静态模式的有效作用量是一个扰动的非拓扑$G_k/G$模型。 在这个模型中，我们计算了 Polyakov 环算符的一圈有效势，并显式构造了低能激发态。 在强耦合极限下，该理论处于去禁闭相。 显示英文摘要

摘要： We show that the problem of computing the vacuum expectation values of gauge invariant operators in the strong coupling limit of topologically massive gauge theory is equivalent to the problem of computing similar operators in the $G_k/G$ model where $k$ is the integer coefficient of the Chern-Simons term. The $G_k/G$ model is a topological field theory and many correlators can be computed analytically. We also show that the effective action for the Polyakov loop operator and static modes of the gauge fields of the strongly coupled theory at finite temperature is a perturbed, non-topological $G_k/G$ model. In this model, we compute the one loop effective potential for the Polyakov loop operators and explicitly construct the low-lying excited states. In the strong coupling limit the theory is in a deconfined phase.
