Abstract

Numerical and holographic models for strongly coupled systems indicated a rise in the vicinity of the confinement – deconfinement phase transition of the quark gluon plasma. We investigate the behaviour of bulk viscosity in holographic models that are 4+1 dimensional Einstein – dilaton gravity theories with potentials that are asymptotically exponential in the IR. We find that in such models where the phase transition is continuous, the bulk viscosity / entropy density ratio has a maximum just above a critical temperature and remains finite.
