Universal conductivity and central charges

Pavel Kovtun, Adam Ritz

Published 2008-05-31, updated 2008-08-21Version 2

We discuss a class of critical models in d>1+1 dimensions whose electrical conductivity and charge susceptibility are fixed by the central charge in a universal manner. We comment on possible bounds on conductivity, as suggested by holographic duality.
