Stabilization of ultracold molecules using optimal control theory

The optimal control theory was used to transfer the highly excited ultracold molecules to the rovibrational ground state. The created molecules were found to be translationally cold, but vibrationally highly excited. The optimal fields contained the transition frequencies required by a good Franck-Condon pumping scheme. It was concluded that the Franck-Condon pumping scheme could produce stable ultracold molecular samples or even stable molecular Bose-Einstein condensates.
