论文摘要
我们以有限的想象角速度在高温下在高温下扰动地计算Polyakov环电位。这种虚构的旋转并不违反因果关系，并且热力学极限是很好的定义。我们在分析上表明，假想的角速度诱导了扰动的限制相，并用作限制物理学的新探针。我们讨论了一个可能的相图，该相图表现出从扰动限制到低温下狭窄相的绝热连续性。我们还提到了通过施加因果关系结合的分析延续中从虚构到实际角速度的微妙之处。
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.
