Confinement-Induced Resonances in Rabi-Coupled Bosonic Mixtures
arXiv:2512.01837 · doi:10.1103/j8zb-pzsq
Abstract
We consider coherently-coupled bosonic mixtures scattering at low energies in the presence of an external confinement along either one or two directions. We exactly solve the two-body scattering problem, showing that for large Rabi coupling the confinement-induced resonance can be displaced towards scattering lengths values much smaller than the oscillator length. Our results make the observation of confinement-induced resonances more tunable and accessible, offering yet another handle for the efficient control of strong interactions in ultracold quantum gases.
