Realising a species-selective double well with multiple-radiofrequency-dressed potentials
Journal of Physics B: Atomic, Molecular and Optical Physics IOP Publishing 53:15 (2020) 155001
Abstract:
Techniques to manipulate the individual constituents of an ultracold mixture are key to investigating impurity physics. In this work, we confine a mixture of hyperfine ground states of 87Rb atoms in a double-well potential. The potential is produced by dressing the atoms with multiple radiofrequencies. The amplitude and phase of each frequency component of the dressing field are controlled to independently manipulate each species. Furthermore, we verify that our mixture of hyperfine states is collisionally stable, with no observable inelastic loss.Coherent splitting of two-dimensional Bose gases in magnetic potentials

Demonstration of an Atomic Frequency Comb Quantum Memory using Velocity-Selective Pumping in Warm Alkali Vapour
Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS 2020-May (2020)
Abstract:
We present the first demonstration of velocity-selective pumping in an atomic vapour to preserve light-matter coherence. Control is illustrated by a subsequent demonstration of an atomic frequency comb quantum memory realised in the vapour.Realising a species-selective double well with multiple-radiofrequency-dressed potentials
