标题： Thermal Monopole Condensation and Confinement in finite temperature Yang-Mills Theories

摘要： 我们研究了颜色禁闭与热阿贝尔单极子之间的联系，这些单极子存在于SU(2)杨-米尔斯理论的去禁闭相中，通过研究当温度从高于禁闭/去禁闭转变温度逼近时，单极子系综的统计性质如何变化。特别是，我们研究了具有多重缠绕的单极子电流分布，这些缠绕对应于两个或多个粒子置换，并证明随着去禁闭温度从上方接近，多重缠绕的数量增加，这与这些对象在去禁闭转变点发生凝聚的现象是一致的。我们还探讨了热单极子的质量问题，表明在不同定义下得到的结果仅在转变附近一致，在此区域单极子质量下降并接近临界温度本身。 显示英文摘要

摘要： We investigate the connection between Color Confinement and thermal Abelian monopoles populating the deconfined phase of SU(2) Yang-Mills theory, by studying how the statistical properties of the monopole ensemble change as the confinement/deconfinement temperature is approached from above. In particular we study the distribution of monopole currents with multiple wrappings in the Euclidean time direction, corresponding to two or more particle permutations, and show that multiple wrappings increase as the deconfinement temperature is approached from above, in a way compatible with a condensation of such objects happening right at the deconfining transition. We also address the question of the thermal monopole mass, showing that different definitions give consistent results only around the transition, where the monopole mass goes down and becomes of the order of the critical temperature itself.
