DESCRIPTION:The holographic AdS/CFT duality of string theory l
ets you study quantum black holes indirectly via t
heir dual field theory states. Most existing studi
es have focused on equilibrium or static quantitie
s\, such as entropies\, temperatures\, etc.\, or n
ear-equilibrium quantities such as thermal Green's
functions\, linear transport coefficients and qua
sinormal modes. We wanted to learn about the real
time\, non-equilibrium dynamics of the field theor
y states and so made numerical simulations of some
holographic matrix models [including flat space (
BFSS) and plane wave (BMN) versions]. More precise
ly\, these are simulations of the classical dynami
cs of the bosonic sectors of these models\, which
should be appropriate for high temperatures. This
is in the same spirit as a molecular dynamics simu
lation of a fluid. I'll present the current result
s from our ongoing analysis of these simulations\,
in which we observe thermalization\, fluctuations
and other behavior. I'll then discuss and invite
your comments on the relations to supergravity bla
ck holes and other future work. The talk is based
on the papers arXiv:1104.5469 and arXiv:1211.3425.
