标题： String Tension and Chern-Simons Fluctuations in the Vortex Vacuum of d=3 Gauge Theory

摘要： 基于三维SU(2)规范理论真空作为磁单极-涡旋凝聚的模型，我们给出了弦张力与由于涡旋缠绕导致的规范不变的Chern-Simons易感性之间定量（如果模型依赖）的关系估计，在作用量中不存在Chern-Simons项的情况下。 我们还给出了这些量与真空能量和规范玻色子质量之间的关系。 易感性和弦张力都源自相同的物理现象：封闭涡旋弦的连接、扭曲和弯曲的拓扑性质。 封闭涡旋弦通过一个复标量场理论来描述，其作用量具有从先前工作推导出的低动量规范理论有效势精确形式的功能形式。 高T现象的应用，包括B+L异常破坏，也被提及。 显示英文摘要

摘要： Based on a model of the d=3 SU(2) pure gauge theory vacuum as a monopole-vortex condensate, we give a quantitative (if model-dependent) estimate of the relation between the string tension and a gauge-invariant measure of the Chern-Simons susceptibility, due to vortex linkages, in the absence of a Chern-Simons term in the action. We also give relations among these quantities and the vacuum energy and gauge-boson mass. Both the susceptibility and the string tension come from the same physics: The topology of linking, twisting, and writhing of closed vortex strings. The closed-vortex string is described via a complex scalar field theory whose action has a precisely-specified functional form, inferred from previous work giving the exact form of a gauge-theory effective potential at low momentum. Applications to high-T phenomena, including B+L anomalous violation, are mentioned.
