Prof Masahito Ueda from the University of Tokyo presents some of the recent developments on the topic of topological excitations of Bose-Einstein condensates, such as the Kibble-Zurek mechanism, knot excitations, non-Abelian vortices, ferrofluidity, and collapsing dynamics of a d-wave superfluid. He also discusses the implications of non-Abelian vortices on quantum turbulence and a nontrivial influence of one type of topological excitation on another.
The lecture is free and open to all. Seating is on a first-come, first-served basis.
Spinor and/or dipolar Bose-Einstein condensates can host a rich variety of topological excitations such as quantized vortices, Dirac and t’Hooft-Polyakov monopoles, and skyrmions due to their internal degrees of freedom and anisotropic nature of the interaction. In this talk, the speaker will present some of the recent developments on this topic such as the Kibble-Zurek mechanism, knot excitations, non-Abelian vortices, ferrofluidity, and collapsing dynamics of a d-wave superfluid. Implications of non-Abelian vortices on quantum turbulence and a nontrivial influence of one type of topological excitation on another will also be discussed.
