Query: Dissipative force on an external quark in heavy quark cloud   Within the finite temperature N = 4 strongly coupled super Yang- Mills, we
compute the dissipative force on an external quark in the presence of evenly
distributed heavy quark cloud. This is computed holographically by constructing
the corresponding gravity dual. We study the behaviour of this force as a
function of the cloud density. Along the way we also analyze the stability of
the gravity dual for vector and tensor perturbations.
