In situ magnetic-field stabilization for quantum-gas experiments
E. Gvozdiovas, A. Valdés-Curiel, Q. -Y. Liang +6
We demonstrate a minimally-destructive in situ technique for measuring and stabilizing slowly-drifting magnetic fields in ultracold-atom experiments. While conventional magnetic-fi…
Characterization of Feshbach resonances in using improved interaction potentials
Jing-Chen Zhang, Paul Julienne, Yu Liu
We characterize Feshbach resonances in all isotopologues of the system with improved interaction potentials. Starting from spectroscopically accurate Mo…
Measurements of diffusion coefficients for rubidium--inert gas mixtures using coherent scattering from optically pumped population gratings
Alexander Pouliot, Eduardo Chomen Ramos, Gehrig Carlse +6
We present comprehensive determinations of the diffusion coefficients at C for trace amounts of naturally abundant Rb atoms in inert, naturally abundant He, Ne,…
Spin structure of diatomic van der Waals molecules of alkali atoms
Jing-Lun Li, Paul S. Julienne, Johannes Hecker Denschlag +1
We theoretically investigate the spin structure of weakly bound diatomic van der Waals molecules formed by two identical bosonic alkali atoms. Our studies were performed using know…
Enhancement of Rydberg Blockade via Microwave Dressing
Deniz Kurdak, Patrick R. Banner, Yaxin Li +4
Experimental control over the strength and angular dependence of interactions between atoms is a key capability for advancing quantum technologies. Here, we use microwave dressing…
On the effect of "glancing" collisions in the cold atom vacuum standard
Stephen P. Eckel, Daniel S. Barker, James A. Fedchak +3
We theoretically investigate the effect of ``glancing" collisions on the ultra-high vacuum (UHV) pressure readings of the cold atom vacuum standard (CAVS), based on either ultracol…
