Maths HEP Lunchtime Seminars: External Fields and the Dynamics of Flavours in Holographic Duals of Large N Gauge Theories

Presented by Arnab Kundu, University of Southern California, Los Angeles

5 December 2008 13:00 in CM221


Using ten dimensional dual string backgrounds, we study aspects of the physics of finite temperature large N SU(N) gauge theories, focusing on the dynamics of fundamental quarks in the presence of an external field. In a background magnetic field we find the quark dynamics lead to spontaneous chiral symmetry breaking and establish a non-trivial phase structure in the temperature-magnetic field plane. We work with two particular dual string backgrounds coming from type IIB and type IIA supergravity and demonstrate how the phase structure emerges. We also comment on the dynamics of flavours in an external electric field.
