Numerical relativity and far-from-equilibrium dynamics

Date: 
Friday 20th September 2013 - 11:00 to 11:45
Venue: 
INI Seminar Room 1
Abstract: 
A variety of gravitational dynamics problems in asymptotically anti-de Sitter (AdS) spacetime are amenable to efficient numerical solution using a common approach involving a null slicing of spacetime based on infalling geodesics, convenient exploitation of the residual diffeomorphism freedom, and use of spectral methods for discretizing and solving the resulting differential equations. After describing the approach, recent results on colliding planar shock waves are presented. The validity of hydrodynamics and the applicability of "local" boost invariance in describing the outgoing flow is examined.
