Descrição

At nonzero temperature, the deconfining phase transition
and the change in non-trivial holonomy can be analyzed using an effective matrix model. The shear, and bulk viscosities are computed
in weak coupling but in non-zero holonomy. (shear viscosity/entropy density) decreases as we approach Td, it is still well above the conformal bound. In contrast, (bulk viscosity/entropy density) is largest at Td, comparable to (shear viscosity/entropy density), then falls off rapidly with increasing temperature and is negligible by 2Td.
