All-Optical Control of Birefringence in a Cold Atomic Ensemble
Apoorva Apoorva, Naudson Lucas Lopes Matias, Bérengère Pinoche +3
We demonstrate all-optical control of birefringence in a cold atomic cloud of ytterbium. By optically dressing the excited state via an off-resonant coupling to…

Collective early-time spontaneous decay of a strongly driven cold atomic ensemble
Daniel Benedicto Orenes, Naudson Lucas Lopes Matias, Apoorva Apoorva +3
In this work we present a numerical and experimental investigation of the collective early-time decay rates of a strongly driven and optically dense cold atomic cloud. We prepare t…

Probing subradiant dynamics in cold atomic ensembles via population and emitted light measurements
Antoine Glicenstein, Daniel Benedicto Orenes, Apoorva Apoorva +2
In this letter, we report on the time- and space-resolved measurement of subradiant excited state population in an ultra-cold atomic cloud of 174Yb atoms. We use a depletion imagin…
