Description
Soliton rings in optical beams have been theoretically and experimentally investigated for their interesting dynamics and connections with novel phenomena, including the formation of non-trivial topological states such as vortices. Density and phase engineering techniques have been proposed to create soliton rings in Bose-Einstein condensates. Here, we explore using a coherent two-photon Raman optical imprinting technique to generate dark soliton rings in a Zeeman spin state of a 87 Rb Bose-Einstein condensate (BEC). The relative intensities and phase of the Raman beams determine the relative populations and phase of the atomic spin states, which can then be measured through atom-optic polarimetry. Dark soliton rings correspond to an annular edge dislocation with a phase jump of π, forcing the density to vanish at the dislocation. We use higher-order Laguerre-Gauss p-modes with the requisite …
