A bstractThe DC thermoelectric conductivities of holographic systems in which translational symmetry is broken can be efficiently computed in terms of the near-horizon data of the dual black hole. By calculating the frequency dependent conductivities to the first subleading order in the momentum relaxation rate, we give a physical explanation for these conductivities in the simplest such example, in the limit of slow momentum relaxation. Specifically, we decompose each conductivity into the sum of a coherent contribution due to momentum relaxation and an incoherent contribution, due to intrinsic current relaxation. This decomposition is different from those previously proposed, and is consistent with the known hydrodynamic properties in the translationally invariant limit. This is the first step towards constructing a consistent theory of charged hydrodynamics with slow momentum relaxation.

Transport in inhomogeneous quantum critical fluids and in the Dirac fluid in graphene (2015, methodology): “[34] was itself inspired by recent progress employing the AdS/CFT correspondence to understand quantum critical transport in strange metals [35, 29, 36, 37, 38, 39, 40, 41, 42], but as we will discuss, this theory is also well suited to describe the physics of graphene.”
