Control and Spectroscopy of Single Molecular Ions
Abstract
Major Goals: The goals of this project were the continued development of spectroscopy techniques for molecular ions co-trapped with atomic ions. This work focused on methods for molecular ion spectroscopy and the preparation of known molecular states. Accomplishments: Key accomplishments included a perspective article that laid out current and future spectroscopy techniques. Some of these techniques have now been implemented by other groups including David Patterson at UC Santa Barbara. A key direction was the testing of the sympathetic cooling of the internal states of molecular ions by interaction with laser-cooled neutral atoms. We were able to show that the interaction of the cooled K atoms and Ca+ ions was negligible. The charge exchange observed is primarily driven by photoexcitation. In collaboration with researchers at UCLA and Emory, we examined the prospects of dipole photon quantum logic using Ca+ and CaO+ and trapped Ca+ and CaO+ together to start the exploration of this work experimentally.
