- Abstract
We investigate the conversion of ultracold bosonic atoms to heteronuclear tetramer AB by an Efimov resonance-assisted stimulated Raman adiabatic passage scheme. In view of recent experiments involving heteronuclear Efimov trimers KKRb and KRbRb [Phys. Rev. Lett. 103, 043201 (2009)], the intermediate state populated by heteronuclear trimer AB in the conversion process is considered. The atom-molecule dark state solution for a system with a population imbalance is derived analytically, and the role played by the imbalance in the conversion is studied. In addition, the effects of the external field parameters (including photoassociated pulse intensity, width, magnetic coupling strength and its detuning) on the conversion are discussed via the concept of adiabatic fidelity.
