最近在零温度和最大中心规范下进行的晶格计算表明，夸克禁闭可以被理解为由于穿透给定威尔逊环的磁涡数量的波动。这一发展导致了涡凝聚理论的复兴。对于SU（2）规范群，我们表明，也在有限的温度下，中心涡是决定长程静态夸克势的相关集体红外自由度;特别是，它们的动力学反映了向退凝相的转变。
Recent lattice calculations performed at zero temperature and in the maximal center gauge indicate that quark confinement can be understood in this gauge as due to fluctuations in the number of magnetic vortices piercing a given Wilson loop. This development has led to a revival of the vortex condensation theory of confinement. For a SU(2) gauge group, we show that also at finite temperatures, center vortices are the relevant collective infrared degrees of freedom determining the long-range static quark potential; in particular, their dynamics reflect the transition to the deconfining phase.
