Events for 2 March 2012
We consider gravity duals for 2+1 dimensional quantum critical points
with anisotropic scaling, where physics at finite temperature and charge density
is described in terms of charged Lifshitz black branes in 3+1 dimensions.
We use a combination of numerics and exact solutions to study equilibrium
thermodynamics of a holographic system exhibiting Lifshitz scaling and present
a simple model for the out-of-equilibrium dynamics following a holographic quench in such systems.
I will consider differential operators which are singular in some sense, in particular differential
operators on infinite domains. With the help of Dirichlet-to-Neumann maps I will study the phenomenon of spectral pollution (or its absence) and how to push pollution out of the way when it does occur.
The talk is based mainly on a single-author paper in IMAJNA (2010) and a recent joint paper with
Rob Scheichl (to appear in J Spectral Theory).
