My research goal is to understand interaction among cold trapped atoms. Such studies are performed using cold Rydberg atoms as well as heteronuclear atomic samples in optical dipole traps. In the Rydberg experiment, long range potentials are responsible for state population transfer. By studying such process, we may obtain information on the potentials. In the heteronuclear sample experiment, our goal is to photoassociate KRb molecules and trap them in an optical dipole trap. We are apply spectroscopy techniques to agriculture problems.
