| Abstract: | The theoretical scheme for the conversion of ultracold atoms to heteronuclear tetrameric molecule is presented.In the framework of the mean field,the dynamical equations describing the process of atom-molecule conversion were analyzed,and the dark states of the system and the corresponding two-photon resonance condition were also derived.The results verified the feasibility of the conversion,and will provide a basis for the formation of complex ultracold molecules in experiment. |
