我们以有限虚角速度扰动计算高温下的波利亚科夫环势。这种假想的旋转并不违反因果关系，并且热力学极限是明确定义的。我们分析表明，虚角速度会引起微扰限制相，并可作为限制物理的新探针。我们讨论了一种可能的相图，该相图表现出低温下从微扰约束到约束相的绝热连续性。我们还提到了通过施加因果关系界限从虚角速度到实角速度的分析延续中的微妙之处。
We perturbatively compute the Polyakov loop potential at high temperature with finite imaginary angular velocity. This imaginary rotation does not violate the causality, and the thermodynamic limit is well defined. We analytically show that the imaginary angular velocity induces the perturbatively confined phase and serves as a new probe to confinement physics. We discuss a possible phase diagram that exhibits adiabatic continuity from the perturbative confinement to the confined phase at low temperature. We also mention subtlety in the analytical continuation from imaginary to real angular velocity by imposing a causality bound.
