Dissipative force on an external quark in heavy quark cloud

Understand

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.
