Controlling the Scattering Length of Ultracold Dipolar Molecules
Controlling the Scattering Length of Ultracold Dipolar Molecules
By applying a circularly polarized and slightly blue-detuned microwave field with respect to the first excited rotational state of a dipolar molecule, one can engineer a long-range, shallow potential well in the entrance channel of the two colliding partners. As the applied microwave ac field is increased, the long-range well …
