Maths HEP Lunchtime Seminars: Holographic Flavor Transport
16 October 2009 13:00 in CM221
Gauge-gravity duality is an extremely useful tool for studying strongly-coupled gauge theories, and has many applications to real-world systems, such as the quark-gluon plasma and quantum critical points. It is especially useful for studying the hydrodynamics of strongly-coupled non-Abelian gauge theories. For example, gauge-gravity duality is currently the only reliable way to compute transport coefficients for many theories. In this talk I will describe a calculation of a transport coefficient, a conductivity, associated with flavor fields in a strongly-coupled plasma. From the result for the conductivity, I will show how gauge-gravity duality captures a lot of real-world physics, such as momentum dissipation, Schwinger pair production, and more.
