论文摘要
我们讨论旋转对两个空间维度的紧凑型电动力学的限制特性的影响，作为一个可分析的模型。我们表明，在有限温度下，旋转导致从距旋转轴一定距离开始的切除过渡。除了通常的限制和解污染阶段外，一个均匀旋转的限制系统还具有混合的不均匀相，该相具有空间分离的限制和解污染区域。因此，相图具有两个不同的解抗温度。第一个切除温度可以通过足够快速的旋转来任意降低，而第二个解束温度在很大程度上不受旋转影响。提出了我们结果对QCD相图的含义。我们指出，当强调从旋转等离子体的核心而不是从其边界开始时，均匀旋转的夸克 - 胶状等离子体应具有反向强膦效应。
We discuss the effects of rotation on confining properties of gauge theories focusing on compact electrodynamics in two spatial dimensions as an analytically tractable model. We show that at finite temperature, the rotation leads to a deconfining transition starting from a certain distance from the rotation axis. A uniformly rotating confining system possesses, in addition to the usual confinement and deconfinement phases, a mixed inhomogeneous phase which hosts spatially separated confinement and deconfinement regions. The phase diagram thus has two different deconfining temperatures. The first deconfining temperature can be made arbitrarily low by sufficiently rapid rotation while the second deconfining temperature is largely unaffected by the rotation. Implications of our results for the phase diagram of QCD are presented. We point out that uniformly rotating quark-gluon plasma should therefore experience an inverse hadronization effect when the hadronization starts from the core of the rotating plasma rather than from its boundary.
