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.
