Change in the adiabatic invariant in a nonlinear two-mode model of Feshbach resonance passage

A. P. Itin, A. A. Vasiliev, S. Watanabe +1

Mean-field approach has recently been used to model coupled atom-molecular Bose-Einstein condensates (BEC) and coupled Fermi-Bose condensates near Feshbach resonance. Sweeping of m…
