Toroidal Transitions in Hydrogenic and Alkali Atoms
Kai Xiang Lee, Vincent Mancois, Kelvin Lim +1
In addition to electric and magnetic multipoles, the expansion of current density also yields toroidal terms, a lesser-known family of multipoles. A recent proposal, I. Kuprov $\te…

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…

Super-resolution optical trapping of multiple cold atoms
Kelvin Lim, Vincent Mancois, Haijun Wu +2
Arrays of optical tweezers form the backbone of neutral atoms analog and digital quantum processors. However, the inter-trap distance remains generally much larger than the size of…
