标题： Center vortex model for the infrared sector of Yang-Mills theory - Confinement and Deconfinement

摘要： 基于用（闭合）随机曲面表示的磁涡流的有限红外区Yang-Mills理论模型被使用格点蒙特卡洛方法研究。 这些随机曲面由面积作用量和曲率作用量控制。 该模型生成了一个有限温度脱禁闭相变；模型的耦合常数可以被选择以重现SU(2) Yang-Mills理论中脱禁闭温度与零温弦张力平方根之比，T_c / sqrt{σ₀}= 0.69。 这在耦合常数空间中定义了一条物理轨迹，在这条轨迹上禁闭性质近似不变。 结果得到了一个乍一看令人惊讶地精确的脱禁闭相中空间弦张力的预测，考虑到该相中涡旋构型的独特时空结构，这一点是可以理解的。 禁闭性质被证明与涡旋表面的渗透性质紧密相关。 显示英文摘要

摘要： A model for the infrared sector of Yang-Mills theory based on magnetic vortices represented by (closed) random surfaces is investigated using lattice Monte Carlo methods. The random surfaces are governed by a surface area action and a curvature action. The model generates a finite-temperature deconfinement transition; the coupling constants of the model can be chosen such as to reproduce the SU(2) Yang-Mills ratio of the deconfinement temperature to the square root of the zero-temperature string tension, T_c / sqrt{sigma_0} =0.69. This yields a physical trajectory in the space of coupling constants on which the confinement properties are approximately invariant. An at first sight surprisingly accurate prediction of the spatial string tension in the deconfined phase results, which can be made plausible in view of the specific space-time structure of the vortex configurations in this phase. The confinement properties are shown to be intimately tied to the percolation properties of the vortex surfaces.
