Deterministic Nucleation and Dynamics of Infilled Multiply-Charged Vortices in an Immiscible ${}^{87}\mathrm{Rb}$-${}^{41}\mathrm{K}$ Mixture

R. Doran, K. E. Wilson

We propose a method for controllably generating multiply-charged vortices in immiscible Bose-Einstein condensates. We achieve this by applying a laser stirring technique to a $^{87…
