Two-color laser modulation of magnetic Feshbach resonances

doi:10.1088/1674-1056/24/8/080308

Abstract We investigate the two-color laser modulation of the magnetically induced Feshbach resonance. The two-color laser is nearly resonant with an optical bound-to-bound transition at the resonance position. The analytical formula of scattering length is obtained by solving the Heisenberg equation. The scattering length can be modified by changing the Rabi frequencies or optical field frequency. By choosing the suitable optical parameters, the two-body loss coefficient K₂ can be greatly reduced compared to the usual single optical scheme.

Keywords: ultracold molecule Feshbach resonance two-body loss coefficient
