摘要

在流体/重力膜范式中研究了具有任意动力学指数的有效李夫希兹黑洞。计算并分析了双 Lifshitz 场理论中的传输和响应系数，包括电荷扩散常数和剪切模阻尼常数，以及剪切粘度与熵密度比。利用久保公式，通过李夫希兹黑球几何中规向量波动的全息线性响应，得到了与杂质相对应的规部门的直流电导。

Effective Lifshitz black holes, hydrodynamics, and transport coefficients in fluid/gravity correspondence

Effective Lifshitz black holes with arbitrary dynamical exponent are addressed in the fluid/gravity membrane paradigm. The transport and the response coefficients in the dual Lifshitz field theory are calculated and analyzed, including the charge diffusion constant and the shear mode damping constant, along with the shear-viscosity-to-entropy density ratio. The Kubo formula is employed to obtain the electrical DC conductivity for the gauge sector corresponding to impurity through the holographic linear response of gauge vector fluctuations in the Lifshitz black brane geometry.
