Abstract

Lattice simulations reveal that the deconfinement-confinement phase transition (PT) of the hot pure SU(N > 2) Yang-Mills system is first order. This system can be described by a pool of quasigluons moving in the Polyakov loop background, and in this picture, we establish an effective distribution function for quasigluons, which encodes interactions among quasigluons and in particular the confinement effect. With it, we made the first attempt to calculate the confinement bubble wall velocity v_w at the microscopical level, and we obtained a small velocity v_w ~ 0.04 using two different approaches, which is qualitatively consistent with others results like holography.

通过准粒子测定约束气泡壁速度

晶格模拟表明，热纯SU（N >）的解除约束相变（PT）；2) Yang-Mills系是一阶的。该系统可以用在Polyakov环背景下运动的准子池来描述，在此图中，我们建立了准子的有效分布函数，该函数编码了准子间的相互作用，特别是约束效应。在此基础上，我们首次尝试在微观水平上计算约束气泡壁速度vw，并通过两种不同的方法得到了一个较小的速度vw ~ 0.04，这与全息等其他方法的结果在质量上是一致的。
