Thermoelectric conductivities, shear viscosity, and stability in an anisotropic linear axion model

Understand

We study thermoelectric conductivities and shear viscosities in a holographically anisotropic model, which is dual to a spatially anisotropic $\mathcal{N}=4$ super-Yang-Mills theory at finite chemical potential.

• Momentum relaxation is realized through perturbing the linear axion field.
• Ac conductivity exhibits a coherent/incoherent metal transition.
• Deviations from the Wiedemann-Franz law are also observed in our model.
