Cold-atom fountain for atom-surface interaction measurements mediated by a near-resonant evanescent light field
Taro Mashimo, Masashi Abe, Athanasios Laliotis +1
Cold atomic ensembles offer precise tools for probing near-field interactions, yet experimental data linking atom dynamics to surface-induced forces remains limited. This study inv…

Multipole expansion for dispersion forces -- watch this trace
Jivesh Kaushal, Chris Boldt, Stefan Scheel +2
Light-matter interaction models invariably rely on the multipole expansion of the electromagnetic potentials generated by complex charge distributions. These multipoles are typical…

Sub-Doppler spectroscopy of Rydberg atoms via velocity selection memory in a hot vapor cell
Esther Butery, Biplab Dutta, Stephany Santos +4
We study resonance redistribution mechanisms inside a hot vapor cell. This is achieved by pumping atoms on the first cesium resonance, 6S1/2-->6P1/2, and subsequently probing the v…
