N-electron multi-configurational spin-coupled wavefunctions for Feshbach resonances

, 1999
It is shown that multi-configurational spin-coupled wavefunctions can be optimized selectively to represent the closed channels of Feshbach resonances in a generalized minimax formulation.

Universal Quantum Dynamics of Bose Polarons

Physical Review X
Predicting the emergent properties of impurities immersed in a quantum bath is a fundamental challenge that can defy quasiparticle treatments. Here, we measure the spectral properties and real-time dynamics of mobile impurities injected into a weakly ...

An asymptotic bound state model to predict Feshbach resonances

, 2009
eshbach resonances play a central role in the manipulation of the interparticle interaction in ultracold atomic gases. The Asymptotic Bound-state Model (ABM) [1,2] is a powerful and easy-to-use tool to predict properties of these Feshbach resonances ...

Large anomalous shifts of potassium-39 Feshbach resonances

We report the observation of large anomalous shifts, up to +7.5 G, of the positions of the 33.6 G and 39.9 G Feshbach resonances in potassium-39 atoms confined in a 1063.9 nm optical dipole trap (ODT) at temperatures up to around 35 μK and trap depths up
