Efficient simulation of Bose-Einstein condensates in nontrivial topologies

Abel Beregi, Jean-Baptiste Gerent, Nathan Lundblad

Bubble-shaped Bose-Einstein condensates (BECs) constitute a unique class of quantum fluids with a hollow, thin-shell geometry that supports a wide variety of phenomena that are dis…

Probing atom-surface interactions from tunneling-time measurements via rotation-transport on an atom chip

J-B. Gerent, R. Veyron, V. Mancois +3

We propose a novel method to measure the interaction between an ultracold gas of neutral atoms and a surface. This solution combines an optical dipole trap reflected by the surface…
