轴向电流中的旋转和加速度效应:密度算符与Wigner函数

Effects of rotation and acceleration in the axial current: density operator vs Wigner function

George Y. Prokhorov, Oleg V. Teryaev, Valentin I. Zakharov

摘要:

本文根据热涡度张量三阶微扰理论中的平衡量子统计密度算符,计算了有质量和无质量费米子情况下轴向流中的流体动力学系数。得到的系数描述手征涡效应的三阶修正,并包括本地加速度的贡献。我们表明,维格纳函数和统计密度算子的方法导致相同的结果,轴向电流在描述与涡量的影响时,当地加速度为零,但不同的是在描述的混合效应,其中加速度和涡量是显着的同时。

英文摘要:

The hydrodynamic coefficients in the axial current are calculated on the basis of the equilibrium quantum statistical density operator in the third order of perturbation theory in thermal vorticity tensor both for the case of massive and massless fermions. The coefficients obtained describe third-order corrections to the Chiral Vortical Effect and include the contribution from local acceleration. We show that the methods of the Wigner function and the statistical density operator lead to the same result for an axial current in describing effects associated only with vorticity when the local acceleration is zero, but differ in describing mixed effects for which both acceleration and vorticity are significant simultaneously.
