Critical and near-critical relaxation of holographic superfluids

Abstract: We investigate the relaxation of holographic superfluids after quenches with end state is either exactly on the critical point, or very close to it. In the former case the system exhibits a power law falloff as well as an emergent discrete scale invariance. Moreover, we postulate a phenomenological Gross–Pitaevskii-like equation that is able to make quantitative predictions for the behavior after near-critical quenches. Intriguingly, within holography all parameters of our phenomenological equation may be fixed with information from the static equilibrium solutions and linear response theory.
