Query: The shear viscosity of gauge theory plasma with chemical potentials   We consider strongly coupled gauge theory plasma with conserved global
charges that allow for a dual gravitational description. We study the shear
viscosity of the gauge theory plasma in the presence of chemical potentials for
these charges. Using gauge theory/string theory correspondence we prove that at
large 't Hooft coupling the ratio of the shear viscosity to the entropy density
is universal.
