Maths HEP Lunchtime Seminars: Quasi-Normal Modes from Non-Commutative Matrix Dynamics

Presented by Francesco Aprile, University of Southampton

24 February 2017 13:00 in CM221

I will describe generic features of the real time dynamics of Dyson-Fluid solutions in non-commutative matrix models, focusing in particular on the BMN matrix model. By quenching the equilibrium distribution is possible to engineer a variety of linear response experiments, and show that the expectation values of several observable display quasi-normal oscillations. I will describe in detail how the corresponding complex frequency depends on the parameters of the model. Finally, I will comment on the interpretation of this statistical systems as a truncated ``classical unit" of finite energy black hole configurations in AdS gravity.
