My research interest is in the physics and chemistry of atoms, ions and molecules at ultralow temperatures. We work on cooling and trapping of ultracold atoms, ions and molecules; cold collisions; creation of ultracold molecules by photoassociation and molecular ions by laser ionization; characterization and manipulation of interactions between these species; optical spectroscopy and cavity based detection of interactions. These ultralow-temperature systems are useful for studies of quantum phase transitions, quantum simulations, and are promising for quantum computing.
