论文摘要
我们重新审视黑洞几何形状与手性运输之间的关系。将异常方程整合在黑洞几何形状中，从而使远离地平线的热气体的手性传输系数得出。关键成分是将协变电流的消失施加到地平线上。我们扩展了该方法，以包括带电黑洞和弱磁场的通常的规格异常。这允许得出描述手性磁和手性涡旋效应的完整运输系数。
We revisit the relation between black hole geometries and chiral transport. Integrating the anomaly equation in a black hole geometry allows to derive the chiral transport coefficients for the thermal gas far from the horizon. The key ingredient is to impose vanishing of the covariant current on the horizon. We extend the method to include the usual gauge anomaly for charged black holes and to weak magnetic fields. This allows to derive the full set of transport coefficients describing the chiral magnetic and chiral vortical effects.
