Diverse vortex dynamics in superfluids

The appearance of quantized vortices is a typical signature of superfluidity which has received a lot of attention in the studies of superfluid Helium, superconductivity and more recently the Bose-Einstein condensation. Recent theoretical and computational studies on the vortex dynamics have shed light on the characteristics of the quantized vortices. Here, we discuss several dynamical systems governing the motion and interaction of quantized vortices and give some computational results that illustrate the diverse nature of vortex dynamics under different driven forces.
