A bstractIn 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…

Holographic lattices give the graviton an effective mass.

It is shown that the presence of the lattice induces an effective mass for the graviton via a gravitational version of the Higgs mechanism, which leads to a power law resistivity that is in agreement with an earlier field theory analysis of Hartnoll and Hofman.
