Matter wave propagation above a step potential within the cubic-nonlinear Schrödinger equation
H. A. Ishkhanyan, A. M. Manukyan, A. M. Ishkhanyan
We analyze the matter wave transmission above a step potential within the framework of the cubic-nonlinear Schrödinger equation. We present a comprehensive analysis of the correspo…
Multiple-scale analysis for resonance reflection by a one-dimensional rectangular barrier in the Gross-Pitaevskii problem
H. A. Ishkhanyan, V. P. Krainov
We consider a quantum above-barrier reflection of a Bose-Einstein condensate by a one-dimensional rectangular potential barrier, or by a potential well, for nonlinear Schroedinger…
Above-Barrier Reflection of Cold Atoms by Resonant Laser Light within the Gross-Pitaevskii Approximation
H. A. Ishkhanyan, V. P. Krainov
Above-barrier reflection of cold alkali atoms by resonant laser light was considered analytically within the Gross-Pitaevskii approximation. Correction for the reflection coefficie…
Weak coupling regime of the Landau-Zener transition for association of an atomic Bose-Einstein condensate
N. Sahakyan, H. Azizbekyan, H. Ishkhanyan +2
In the framework of a basic semiclassical time-dependent nonlinear two-state problem, we study the weak coupling limit of the nonlinear Landau-Zener transition at coherent photo- a…
