Density profiles of two-component Bose-Einstein condensates interacting with a Laguerre-Gaussian beam

The density profiles of trapped two-component Bose-Einstein condensates (BEC) and its microscopic interaction with Laguerre-Gaussian (LG) beam are studied. We consider the 87Rb BEC in two hyperfine spin components. The wavelength of the LG beam is assumed to be comparable to the atomic de Broglie wa...

Description
Summary:The density profiles of trapped two-component Bose-Einstein condensates (BEC) and its microscopic interaction with Laguerre-Gaussian (LG) beam are studied. We consider the 87Rb BEC in two hyperfine spin components. The wavelength of the LG beam is assumed to be comparable to the atomic de Broglie wavelength. Competitions between intra- and inter-component interactions produce interesting density structures of the ground state of BEC. We demonstrate vortex-antivortex interference and its dependence on the inter-component interactions and Raman transitions.
