Description

We study the properties of heavy quarks as probes of strongly coupled plasmas with non-zero chemical potential by means of deformations of the gauge/gravity (AdS/CFT) duality. We compute the screening distance of a heavy quark-antiquark pair, its free energy, and the running coupling, as well as the drag force experienced by a single quark in large classes of models. The screening distance and the free energy exhibit some insensitivity concerning the choice of model and deformation, pointing to strong-coupling universal behavior that depends only weakly on the microscopic details. Thus, our results may be relevant for modeling heavy quarkonia traversing a quark-gluon plasma at finite net baryon density, and their suppression by melting.
