有限温度杨-米尔斯理论中的热单极凝聚和限制

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

Alessio D'Alessandro, Massimo D'Elia, Edward Shuryak

摘要:

通过研究SU(2)Yang-Mills理论的色禁闭和热阿贝尔单极子之间的联系,我们研究了色禁闭和热阿贝尔单极子的统计性质如何随着禁闭/解除禁闭温度的变化而变化。特别是,我们研究了在欧几里得时间方向上具有多个包裹的电流分布,对应于两个或更多个粒子排列,并表明多个包裹随着从上面接近解除禁闭温度而增加,以与发生在解除禁闭过渡处的此类对象的冷凝相容的方式。我们还解决的问题的热膨胀质量,表明不同的定义给出一致的结果,只有周围的过渡,在那里的热膨胀质量下降,并成为临界温度本身的顺序。

英文摘要:

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.
