报告摘要:

I will report ourrecent numerical advance on the non-equilibrium dynamics of holographicsuperfluids. In particular, I will talk about the dynamical instability of darksoliton, where a novel dynamical phase transition has been found between theacceleration instability and snake instability, which may be tested by the coldatom experiments. In addition, if time permits, i also like to talk about theonset of quantum wave turbulence and its holographic characterization, which isdirectly relevant to the recent cold atom experiment by the Cambridge group.
