I will explore the far from equilibrium response of a superfluid using the gauge-gravity duality (also known as `AdS/CFT'). This duality, mapping a quantum critical theory to one involving gravity, has emerged in recent years as a powerful tool in the study of strongly coupled systems. Using this approach I will establish the dynamical phase diagram corresponding to quantum quenches of the order parameter source field. The resulting setup can be solved in great detail even far from equilibrium and gives rise to three distinct dynamical regimes (phases). I will end with some comments about the genericity of this behavior found for time-reversal invariant systems with broken symmetry.
