The role of particle interactions in a many-body model of Feshbach molecular formation in bosonic systems
Jing Li, Di-Fa Ye, Chao Ma +2
In this paper, we investigate the atom-molecule conversion dynamics of a generalized many-body model that includes the atom-atom, atom-molecule, and molecule-molecule interactions,…
Rosen-Zener interferometry with Ultracold Atoms
Li-Bin Fu, Di-Fa Ye, Chaohong Lee +2
We propose a time-domain "interferometer" based on ultracold Bose atoms loaded on a double well potential. By the adiabatic Rosen-Zener process, the barrier between two wells is ra…
Rosen-Zener Transition in a Nonlinear Two-Level System
Di-Fa Ye, Li-Bin Fu, Jie Liu
We study Rosen-Zener transition (RZT) in a nonlinear two-level system in which the level energies depend on the occupation of the levels, representing a mean-field type of interact…
Landau-Zener Tunnelling in a Nonlinear Three-level System
Guan-Fang Wang, Di-Fa Ye, Li-Bin Fu +2
We present a comprehensive analysis of the Landau-Zener tunnelling of a nonlinear three-level system in a linearly sweeping external field. We find the presence of nonzero tunnelli…
