Instability, adiabaticity, and controlling effects of external fields for the dark state in a homonuclear atom–tetramer conversion system

doi:10.1088/1674-1056/23/4/040306

Abstract In the present paper, we investigate the instability, adiabaticity, and controlling effects of external fields for a dark state in a homonuclear atom-tetramer conversion that is implemented by a generalized stimulated Raman adiabatic passage. We analytically obtain the regions for the appearance of dynamical instability and study the adiabatic evolution by a newly defined adiabatic fidelity. Moreover, the effects of the external field parameters and the spontaneous emissions on the conversion efficiency are also investigated.

Keywords: dynamical instability adiabatic fidelity dark state atom-molecule conversion
