Maths HEP Lunchtime Seminars: Deriving the hydrodynamical description of holographic superfluids

Presented by Julian Sonner, Imperial

19 November 2010 13:00 in CM221

In my talk I will describe a class of gravitational solutions which, in the context of AdS/CFT, are dual to boundary field theories with spontaneous symmetry breaking and thus give rise to a superfluid phase. I will use the tools of gauge/gravity duality to demonstrate that the boundary description of such systems, in the hydrodynamical limit, is governed by a relativistic generalisation of the Tisza-Landau two-fluid model. I will establish this model to non-dissipative order and will comment on its relevance to computing higher-order transport coefficient in the presence of a non-vanishing symmetry-breaking condensate.
