Description

The transport properties of dense QCD matter play a crucial role in the physics of neutron stars and their mergers, but are notoriously difficult to study with traditional quantum field theory tools. Specializing to the case of unpaired quark matter in beta equilibrium, we approach the problem through the machinery of holography, and derive results for the electrical and thermal conductivities and the shear and bulk viscosities. Our results differ dramatically from earlier predictions of perturbative QCD, the root causes and implications of which we analyze in detail.
