Universality of second order transport coefficients from the gauge-string duality

arXiv:0811.1794 · doi:10.1016/j.nuclphysb.2008.12.028

Abstract

We consider the strongly coupled limit of conformal gauge theory plasmas with conserved U(1) charges which have a gravity dual. We show that, under mild restrictions, the second order transport coefficients of such theories satisfy a universal relation among themselves, similar to the shear viscosity to entropy ratio.
