Title: Dissipative force on an external quark in heavy quark cloud
Date: Tue, Jan 24, 2012, 13:15 - 14:45
Place: Seminar Room A
Abstract: For 30 minute talk:
QGP is a de-confined phase of QCD. An external heavy quark moving through the QGP medium at finite temperature experiences dissipative force. We estimate the dissipative force using gauge/gravity duality.

For 1 hour talk:
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.
