加速物质中的手征涡旋效应

On chiral vortical effect in accelerated matter

P. G. Mitkin, V. I. Zakharov

摘要:

我们重新评估的手征涡效应在加速的物质。对于加速度中的一阶,轴向电流的相应矩阵元素可以从平坦空间极限重构。一个关键点是在这种情况下存在一个额外的流体螺旋度守恒定律。因此,微观自由度的手征性和宏观运动的螺旋性分别守恒。这种分离在重力存在的情况下也持续存在。的热手征涡效应的影响进行了讨论。

英文摘要:

We revisit the evaluation of the chiral vortical effect in the accelerated matter. To first order in the acceleration the corresponding matrix element of the axial current can be reconstructed from the flat-space limit. A crucial point is the existence in the this case of an extra conservation law of fluid helicity. As a result, the chirality of the microscopic degrees of freedom and helicity of the macroscopic motion are separately conserved. This separation persists also in presence of gravity. Implications for the thermal chiral vortical effect are discussed.
