Manipulating transition of a two-component Bose-Einstein condensate with a weak δ-shaped laser

doi:10.1088/1674-1056/ab3e64

Abstract

We theoretically study the transition dynamics of a two-component Bose-Einstein condensate driven by a train of weak δ-shaped laser pulses. We find that the atomic system can experience peculiar resonant transition even under weak optical excitations and derive the resonance condition by the perturbation method. Employing this mechanism, we propose a scheme to obtain an atomic ensemble with desired odd/even atom number and also a scheme to prepare a nonclassical state of the many-body system with fixed atom number.

Keywords: two-component Bose-Einstein condensate quantum kicked top model nonclassical state
