The Odom Research Group is developing new technology to manipulate trapped molecular ions. In most of these efforts, molecular ions held in radiofrequency Paul traps are sympathetically cooled to below 1 Kelvin, through their Coulomb interaction with co-trapped laser-cooled atomic ions. We are developing techniques to cool not only the motion of the trapped molecular ions but also their rotations and vibrations. Having technology to obtain molecular ions which are cold both in their internal and external degrees of freedom would open up a range of new applied physics possibilities, including coherent control, molecular alignment and orientation, and quantum computing.
