TL;DR
This paper demonstrates that hyperfine Rabi oscillations can stabilize a two-dimensional Bose-Einstein condensate droplet in free space by inducing time-dependent effective interactions, analyzed through a two-component Gross-Pitaevskii model.
Contribution
It introduces a novel stabilization method for Bose-Einstein condensate droplets using hyperfine Rabi oscillations, supported by variational analysis.
Findings
Stability achieved in two-dimensional free space
Effective interaction oscillates in time due to Rabi oscillations
Parameter regime for stable droplets identified
Abstract
A self-trapped Bose-Einstein condensate is shown to be stabilized in two-dimensional free space by Rabi oscillations between two hyperfine states which make an effective interatomic interaction oscillate in time. The stabilization mechanism is elucidated by using a two-component Gross-Pitaevskii equation combined with a variational analysis. The parameter regime of stability is investigated.
