Aligning and Trapping Molecules with Light

L. Kador

An alternative to matrix isolation, cold molecules can be trapped and aligned in vacuum by an intense infrared laser field according to theoretical considerations expounded recently. The method is based on the polarization of the molecules by the electric field of the light, which creates an attractive potential. If the polarizability of the molecules is anisotropic, the axis of highest polarizability will be aligned along the polarization direction of the laser.

Multi-channel modelling of the formation of vibrationally cold polar KRb molecules

Svetlana Kotochigova, Eite Tiesinga, Paul S. Julienne

We describe the theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar 40 K 87 Rb molecules [1,2].Cold molecules were created from very-weakly bound molecules formed by magnetic field sweeps near a Feshbach resonance in collisions of ultra-cold 40 K and 87 Rb atoms.Our analysis include the multi-channel bound-state calculations of the hyperfine and Zeeman mixed X 1 + and a 3 + vibrational levels.We find excellent agreement with the hyperfine structure observed in experimental data.In addition, we studied the spin-orbit mixing in the intermediate state of the Raman transition.This allowed us to investigate its effect on the vibrationally averaged transition dipole moment to the lowest rovibrational level of the X 1 + state.Finally, we obtained an estimate of the polarizability of the initial and final rovibrational states of the Raman transition near frequencies relevant for optical trapping of the molecules.Contents 1.
