Dynamics of a many-particle Landau-Zener model: inverse sweep
A. P. Itin, P. Törmä
We consider dynamics of a slowly time-dependent Dicke model, which represents a many-body generalization of the Landau-Zener model. In particular, the model describes narrow Feshba…

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…

Universality in nonadiabatic behaviour of classical actions in nonlinear models with separatrix crossings
A. P. Itin, S. Watanabe
We discuss dynamics of approximate adiabatic invariants in several nonlinear models being related to physics of Bose-Einstein condensates (BEC). We show that nonadiabatic dynamics…
