Observation of an orbital interaction-induced Feshbach resonance in 173-Yb
M. Höfer, L. Riegger, F. Scazza +6
We report on the experimental observation of a novel inter-orbital Feshbach resonance in ultracold 173-Yb atoms, which opens the possibility of tuning the interactions between the…
Magnetism in strongly interacting one-dimensional quantum mixtures
Pietro Massignan, Jesper Levinsen, Meera M. Parish
We consider two species of bosons in one dimension near the Tonks-Girardeau limit of infinite interactions. For the case of equal masses and equal intraspecies interactions, the sy…
Impurity in a Bose-Einstein condensate and the Efimov effect
Jesper Levinsen, Meera M. Parish, Georg M. Bruun
We investigate the zero-temperature properties of an impurity particle interacting with a Bose-Einstein condensate (BEC), using a variational wavefunction that includes up to two B…
Quasiparticle properties of a mobile impurity in a Bose-Einstein condensate
Rasmus Søgaard Christensen, Jesper Levinsen, Georg M. Bruun
We develop a systematic perturbation theory for the quasiparticle properties of a single impurity immersed in a Bose-Einstein condensate. Analytical results are derived for the imp…
