Survival resonances in an atom-optics system driven by temporally and spatially periodic dissipation
journal contribution
posted on 2023-06-09, 13:42 authored by Shijie Chai, Julia FeketeJulia Fekete, Peter McDowall, Simon Coop, Thue Lindballe, Mikkel F AndersenWe investigate laser-cooled atoms periodically driven by pulsed standing waves of light tuned close to an open atomic transition. This nonunitary system displays survival resonances for certain driving frequencies. The survival resonances emerge as a result of the matter-wave Talbot-Lau effect, similar to the Talbot effect causing quantum resonances in the atom optics d-kicked rotor. Since the Talbot-Lau effect occurs for incoherent waves, the survival resonances can be observed using thermal atoms. A microlensing effect can enhance the height and incisiveness of the resonances. This may find applications in precision measurements.
