报告摘要：

  Vortex dynamics plays a fundamental role in turbulence. In this talk, I will report our very recent work on splitting dynamics of multiply quantized vortex in superfluid via the lens of holographic duality, which relates the strongly coupled many body quantum systems to the weakly interacting gravitational systems and is particularly suitable to address the non-equilibrium process, which is otherwise notoriously difficult to attack by conventional methods. In particular, we discover some universal novel behaviors associated with the splitting dynamics of the multiply quantized vortex, which is amenable to verification in the tabletop experiments in cold atom gases.
