Formation of a heteronuclear tetramer A3B via Efimov-resonance-assisted stimulated Raman adiabatic passage.

We investigate the formation of a heteronuclear tetramer A3B by an Efimov-resonance-assisted stimulated Raman adiabatic passage scheme, which is considered a viable means of creating the homonuclear tetramer A4 [H. Jing and Y. Jiang, Phys. Rev. A 77, 065601 (2008)]. The atom-molecule dark-state solution for the system is derived, and the adiabatic conversion from atoms to heteronuclear tetramers is studied via the concept of adiabatic fidelity. In addition, the effects of external field parameters (including Rabi pulse strength, width, and single photon detuning) on the conversion are discussed. [ABSTRACT FROM AUTHOR]
