| Research Abstract |
We studies superfluid properties of Bose-Einstein condensates (BECs) with internal degrees of freedom. We have numerically demonstrated that by changing an external magnetic field spin vortices are spontaneously generated. This provides an atomic-gas demonstration of the Kibble-Zurek mechanism. We have also demonstrated that exotic topological excitations such as knots and non-Abelian vortices can be created in spinor BECs.
