Resonant enhancement of particle emission from a parametrically driven condensate in a one-dimensional lattice
arXiv:2205.01900 · doi:10.1103/PhysRevA.106.033302
Abstract
Motivated by recent experiments, we investigate particle emission from a Bose-Einstein condensate in a one-dimensional lattice, where the interaction strength is periodically modulated. The modulated interactions parametrically excite a collective mode, leading to density oscillations. These collective oscillations in turn drive particle emission. This multistep process amplifies the drive, producing larger particle jets. We find that the amplitude dependence of the emission rate has a characteristic threshold behavior, as seen in experiments.
