重力非线性磁流体力学
Nonlinear Magnetohydrodynamics from Gravity
摘要:
我们应用最近建立的非线性流体动力学和AdS引力之间的联系的情况下,在AdS_4的双离子黑膜。由此得到背景磁场中2+1维带电流体的流体动力学方程。在导数展开中构造了二阶引力解。从这一点上,我们发现流体动力学应力张量和电荷流的二阶和三阶导数分别,以及相关的输运系数的值。
英文摘要:
We apply the recently established connection between nonlinear fluid dynamics and AdS gravity to the case of the dyonic black brane in AdS_4. This yields the equations of fluid dynamics for a 2+1 dimensional charged fluid in a background magnetic field. We construct the gravity solution to second order in the derivative expansion. From this we find the fluid dynamical stress tensor and charge current to second and third order in derivatives respectively, along with values for the associated transport coefficients.
