报告摘要：I will report our recent numerical advance on the non-equilibrium dynamics of holographic superfluids. In particular, I will talk about the dynamical instability of dark soliton, where a novel dynamical phase transition has been found between the acceleration instability and snake instability, which may be tested by the cold atom experiments. In addition, if time permits, i also like to talk about the onset of quantum wave turbulence and its holographic characterization, which is directly relevant to the recent cold atom experiment by the Cambridge group.
