Feshbach resonances in an ultracold ${}^7$Li-${}^{133}$Cs Bose-Bose mixture

Abstract

We present a study of interspecies Feshbach resonances in ultracold ${}^7$Li-${}^{133}$Cs Bose-Bose mixtures. We locate ten interspecies resonances in three different spin-state combinations. By comparing to coupled-channel calculations, we assign six of the resonances to $s$-wave channels and the rest to $p$-wave channels. We use the $s$-wave resonances to refine the ground-state potentials of LiCs in the coupled-channel calculations and then obtain an accurate characterization of the scattering and bound-state properties of the mixtures. Our results will be useful for future experiments with ultracold ${}^7$Li-${}^{133}$Cs mixtures.
