CPT Student Seminar: Generalised Einstein Relations for Inhomogeneous Media

Presented by Vaios Ziogas, University of Durham

29 May 2017 12:30 in OC218

In this talk we are going to study hydrodynamics on curved manifolds. We place the underlying quantum field theory on curved space with a spatially periodic metric and chemical potential and we derive the Navier-Stokes equations after the application of an electric field and a thermal gradient. We show how the diffusive dispersion relations are related to the DC conductivity and certain thermodynamic susceptibilities, thus obtaining generalised Einstein relations. Finally, we comment on the derivation of these relations in the context of holographic CFTs.
