We have created vortices in two-component Bose-Einstein condensates. The vortex state was created through a coherent process involving the spatial and temporal control of interconversion between the two components. Using an interference technique, we map the phase of the vortex state to confirm that it possesses angular momentum. We can create vortices in either of the two components and have observed differences in the dynamics and stability.

Vortices in two-component Bose–Einstein condensates
We study the spatial distribution of particles in two-component Bose–Einstein condensates containing vortices. We show that the form in which the species are arranged inside the condensate may be
Observation of vortex phase singularities in Bose-Einstein condensates.
TLDR
The velocity dependence for vortex excitation and the time scale for re-establishing a uniform phase across the condensate were determined.
Vortices in a stirred Bose-Einstein condensate
Abstract We stir with a focused laser beam a Bose-Einstein condensate of 87Rb atoms confined in a magnetic trap. We observe the formation of a single vortex for a stirring frequency exceeding a
Stability of a Vortex in Spinor Bose-Einstein Condensate
We propose a method to create a vortex in BEC utilizing the spin degree of freedom. We consider the optical plug at the center of the vortex, which makes the vortex-creation process stable. We also
Nontopological vortex in a two-component Bose-Einstein condensate
We present a systematic study on a class of stable vortex solutions in a two-component Bose-Einstein condensate. They are nontopological in nature and possess continuous angular momenta. When coupled
Stability of a single vortex in a trapped Bose-Einstein condensate
Abstract. We investigate the lowest state of a Bose-Einstein condensate with an off-center vortex state that is confined in a rotating harmonic potential. Our results are consistent with the fact
Topological Structure of Vortices in Multicomponent Bose-Einstein Condensates
The structure of the vortex in a two-component Bose—Einstein condensate is studied by the method of Dirac δ function. The vortex can be characterized by the Brouwer degree and Hopf index, i.e., β1η1,
Vortices in atomic Bose–Einstein condensates: an introduction
The occurrence of vortices in atomic Bose–Einstein condensates (BECs) enables a description of their superfluid behavior. In this article, we present a pedagogical introduction the vortex physics in
Vortex trimer in three-component Bose-Einstein condensates
Vortex trimer is predicted in three-component Bose-Einstein condensates with internal coherent couplings. The molecule is made by three constituent vortices which are bounded by domain walls of the
Vortex nucleation through edge states in finite Bose–Einstein condensates
We study the vortex nucleation in a finite Bose–Einstein condensate. Using a set of non-local and chiral boundary conditions to solve the Schrodinger equation of non-interacting bosons in a rotating
