Expansions of the solutions of the biconfluent Heun equation in terms of incomplete Beta and Gamma functions
T. A. Ishkhanyan, Y. Pashayan-Leroy, M. R. Gevorgyan +2
Starting from equations obeyed by functions involving the first or the second derivatives of the biconfluent Heun function, we construct two expansions of the solutions of the bico…
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…
Change in the adiabatic invariant in a nonlinear Landau-Zener problem
R. Sokhoyan, D. Melikdzhanian, C. Leroy +2
We study a nonlinear generalization of the Landau-Zener resonance-crossing problem relevant to coherent photo- and magneto-association of ultracold atoms. Due to the structure of t…
Theory of bright-state stimulated Raman adiabatic passage
G. G. Grigoryan, G. V. Nikoghosyan, T. Halfmann +3
We describe analytically and numerically the process of population transfer by stimulated Raman adiabatic passage through a bright state when the pulses propagate in a medium. Limi…
