DESCRIPTION:For weakly interacting systems\, transport coeffic
ients can be computed\nby applying the standard me
thods of the kinetic theory. At strong\ncoupling\,
however\, these methods are inapplicable. Yet\, t
here are\nstrongly coupled systems exhibiting hydr
odynamic behavior: hot and\ndense nuclear matter p
roduced in heavy ion collisions and cold trapped\n
atoms are the best known examples. A search for ef
fective\nnon-perturbative methods for computing tr
ansport in strongly\ninteracting theories is thus
a necessity.\n\nGauge-gravity duality is a useful
tool for addressing this problem. We\nreview the p
rogress in applying the duality to finite-temperat
ure\nquantum field theory. In particular\, we show
how the hydrodynamic\nbehavior of field theory is
reflected in the low-momentum limit of\ncorrelati
on functions computed through a real-time gauge-gr
avity\nprescription from dual\ngravity. We also sh
ow how the hydrodynamic modes in field theory\ncor
respond to the\nlow-lying quasinormal modes of the
dual gravity background.\n\n
