Query: Transport at criticality   We study second order phase transitions in non-conformal holographic models
of gauge theory/string theory correspondence at finite temperature and zero
chemical potential. We compute critical exponents of the bulk viscosity near
the transition and interpret our results in the framework of available models
of dynamical critical phenomena. Intriguingly, although some of the models we
discuss belong to different static universality classes, they appear to share
the same dynamical critical exponent.
