论文摘要
我们考虑具有外部磁场的磁水动力学。我们发现,一般而言,必须允许非零不连贯的霍尔电导率正确地描述磁场扩展中零阶的直流纵向和霍尔导电电导率。我们将结果应用于敌对的黑洞,确定了这种情况下的不连贯的霍尔电导率,并证明该传输系数的存在导致水力动力学和AC热电器相关器之间的匹配明显更好。
We consider magnetohydrodynamics with an external magnetic field. We find that in general one must allow for a non-zero incoherent Hall conductivity to correctly describe the DC longitudinal and Hall thermal conductivities beyond order zero in the magnetic field expansion. We apply our result to the dyonic black hole, determining the incoherent Hall conductivity in that case, and additionally prove that the existence of this transport coefficient leads to a significantly better match between the hydrodynamic and AC thermo-electric correlators.
