论文摘要
我们考虑光子涡旋效应，即沿旋转光子培养基中角速度沿角速度的左手和右光子的流量差。考虑了两个评估效果的替代框架，两者在文献中已经尝试过。首先，标准的热率理论以及霍金辐射型推导。在我们较早地比较两种方法的尝试中，我们发现了两个差异的关键因素。在这里，我们重新审视了这个问题，更多地关注红外正规化的细节。我们发现，载体场的无限质量的引入将评估手性涡旋效应的两种方式彼此一致。提到了一些在理论和现象学方面的含义。
We consider photonic vortical effect, i.e. the difference of the flows of left- and right-handed photons along the vector of angular velocity in rotating photonic medium. Two alternative frameworks to evaluate the effect are considered, both of which have already been tried in the literature. First, the standard thermal fied theory and, alternatively, Hawking-radiation-type derivation. In our earlier attempt to compare the two approaches, we found a crucial factor of two difference. Here we revisit the problem, paying more attention to details of infrared regularizations. We find out that introduction of an infinitesimal mass of the vector field brings the two ways of evaluating the chiral vortical effect into agreement with each other. Some implications, both on the theoretical and phenomenological sides, are mentioned.
