论文摘要
在仪表理论中，量规不间断的希尔伯特空间与任意当地运营商的耦合没有改变。但是，在威尔逊循环的情况下，必须通过沿环路添加测试电荷来扩大物理希尔伯特空间。我讨论在非零温度下，Polyakov回路与测试电荷的传播器自然相关。 'thooft循环代表测试磁电荷的传播，因此不要改变物理希尔伯特空间。
In a gauge theory, the gauge invariant Hilbert space is unchanged by the coupling to arbitrary local operators. In the presence of Wilson loops, though, the physical Hilbert space must be enlarged by adding test electric charges along the loop. I discuss how at nonzero temperature Polyakov loops are naturally related to the propagator of a test charge. 't Hooft loops represent the propagation of a test magnetic charge, and so do not alter the physical Hilbert space.
