We employ the AdS/CFT correspondence and numerical relativity techniques to investigate the far-from-equilibrium dynamics of a strongly coupled non-Abelian plasma with a critical point [1] in the temperature and chemical potential phase diagram. In the case of an out-of-equilibrium homogeneous medium [2], isotropization happens before the system thermalizes and the behavior of the pressure anisotropy changes qualitatively as the chemical potential is increased towards the critical point. These results are then generalized [3] to consider the case of an expanding plasma undergoing Bjorken flow in the vicinity of the critical point, which allows us to determine for the first time how the presence of a critical point affects the emergence of hydrodynamic behavior (hydrodynamization) in a strongly coupled plasma similar to the Quark-Gluon Plasma formed in the RHIC beam energy scan. The interplay between critical phenomena and non-equilibrium hydrodynamic attractor solutions in Bjorken flow [3] will be also discussed.
