"Transport Properties of Strongly Coupled Gauge Theories from String Theory"

Presented by Andrei Starinets, Perimeter Institute for Theoretical Physics, Ontario, Canada

Thursday, February 23, 2006, 12:00 pm — Building 510, Room 2-160

Assuming the AdS/CFT conjecture is valid, transport properties of certain strongly coupled thermal gauge theories can be determined from their effective description in terms of gravity or superstring theory duals. We review the results for the shear and bulk viscosity, thermal conductivity, charge diffusion constant, and the speed of sound in supersymmetric strongly interacting plasmas and comment on the relation of these results to RHIC physics. We also outline a general algorithm for computing transport coefficients in any gravity dual. The algorithm relates the
transport coefficients to the quasinormal spectrum of five-dimensional black holes in asymptotically anti de Sitter space.
