CONVERSION FROM ATOMIC TO MOLECULAR BOSE–EINSTEIN CONDENSATE VIA CHAINWISE ADIABATIC PASSAGE
Jian Li, Yong Liu, Shu‐Lin Cong
We present an approach for effectively converting atomic Bose–Einstein condensate (BEC) into molecular one. Atoms are converted into molecules through a series of intermediate vibrational states by using chainwise stimulated Raman adiabatic passage technique. We utilize a feasible pulse sequence to achieve higher conversion efficiency by solving the coupled mean-field equations. As an example, we investigate the formation of Rb 2 and calculate conversion efficiency to be 92.3%.
