Complete-return spectrum for a generalized Rosen-Zener two-state term-crossing model
T. A. Shahverdyan, D. S. Mogilevtsev, V. M. Red'kov +1
The general semiclassical time-dependent two-state problem is considered for a specific field configuration referred to as the generalized Rosen-Zener model. This is a rich family…
Demkov-Kunike model in cold molecule formation
A. Ishkhanyan
We study the dynamics of cold molecule formation via photo- or magneto-association of quantum degenerate atomic gases for the case when the field configuration is defined by the qu…
Landau-Zener transition in quadratic-nonlinear two-state systems
A. M. Ishkhanyan
A comprehensive theory of the Landau-Zener transition in quadratic nonlinear two-state systems is developed. A compact analytic formula involving elementary functions only is deriv…
Generalized formula for the Landau-Zener transition in interacting Bose-Einstein condensates
A. M. Ishkhanyan
We present a rigorous analysis of the generalized Landau-Zener problem for the two-level interacting Bose-Einstein condensates. We show that the dynamics of the system is accuratel…
Quadratic-nonlinear Landau-Zener transition for association of an atomic Bose-Einstein condensate with inter-particle elastic interactions included
A. Ishkhanyan, R. Sokhoyan, K. -A. Suominen +2
We study the strong coupling limit of a quadratic-nonlinear Landau-Zener problem for coherent photo- and magneto-association of cold atoms taking into account the atom-atom, atom-m…
Demkov-Kunike model for cold atom association: weak interaction regime
R. Sokhoyan, H. Azizbekyan, C. Leroy +1
We study the nonlinear mean-field dynamics of molecule formation at coherent photo- and magneto-association of an atomic Bose-Einstein condensate for the case when the external fie…
