Magnetotransport from the fluid/gravity correspondence

Understand

We continue our construction of a hydrodynamical description of a holographic model with broken translation invariance.

• Using the fluid/gravity correspondence we derive the constitutive relations of the boundary theory in the presence of a magnetic field.
• This allows us to obtain novel results for the low-frequency magnetothermoelectric response coefficients.
• We discuss the DC limit of our hydrodynamics in detail, and show that our approach is equivalent to the `horizon-fluid' of Donos and Gauntlett.
