Maths HEP Lunchtime Seminars: Thermoelectric DC conductivities and Stokes flows on black hole horizons
23 October 2015 13:00 in CM221
We will consider a general class of electrically charged black holes of Einstein- Maxwell-scalar theory that are holographically dual to conformal field theories at finite charge density, and which break translation invariance explicitly. By examining the linearised perturbations about the solutions that are associated with the thermoelectric DC conductivity, I’ll demonstrate that there is a decoupled sector at the black hole horizon which must solve generalised Stokes equations for a charged fluid. By solving these equations, we can obtain the DC thermoelectric conductivity of the dual field theory.
