Laser spectroscopy of aromatic molecules with optical cycling centers: strontium (I) phenoxides

Guanming Lao, Guo-Zhu Zhu, Claire E. Dickerson +5

We report the production and spectroscopic characterization of strontium (I) phenoxide (, or SrOPh) and variants featuring electron-withdrawing groups…

Functionalizing Aromatic Compounds with Optical Cycling Centers

Guo-Zhu Zhu, Debayan Mitra, Benjamin L. Augenbraun +9

Molecular design principles provide guidelines for augmenting a molecule with a smaller group of atoms to realize a desired property or function. We demonstrate that these concepts…

Increase of barium ion-trap lifetime via photodissociation

Hao Wu, Michael Mills, Elizabeth West +2

The lifetime of Ba ions confined in a Paul trap is found, under typical conditions, to be limited by chemical reactions with residual background gas. An integrated ion trap and…

Dipole-phonon quantum logic with trapped polar molecular ions

Wesley C. Campbell, Eric R. Hudson

The interaction between the electric dipole moment of a trapped molecular ion and the configuration of the confined Coulomb crystal couples the orientation of the molecule to its m…

Engineering excited-state interactions at ultracold temperatures

Michael Mills, Prateek Puri, Ming Li +5

Using a recently developed method for precisely controlling collision energy, we observe a dramatic suppression of inelastic collisions between an atom and ion (Ca + Yb) at low…

High-resolution collision energy control through ion position modulation in atom-ion hybrid systems

Prateek Puri, Michael Mills, Elizabeth P. West +2

We demonstrate an ion shuttling technique for high-resolution control of atom-ion collision energy by translating an ion held within a radio-frequency trap through a magneto-optica…
