Magnetothermoelectric response from holography.

Blake, M. and Donos, A. and Lohitsiri, N. (2015) 'Magnetothermoelectric response from holography.', Journal of high energy physics., 2015 (8). p. 124.


In this note we study the effects of a magnetic field on transport using holographic models with broken translational invariance. We show that, after carefully sub-tracting off non-trivial magnetisation currents, it is possible to express the DC transport currents of the boundary theory in terms of properties of a black hole horizon. This allows us to obtain simple analytic expressions for the electrical, thermoelectric and heat conductivity tensors. Our results apply to both isotropic and anisotropic models, including holographic Q-lattices and to certain theories where translational invariance is broken by linear sources for axions.
