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 alkaline-earth monoxide and monosulfide cations
Michael Mills, Hao Wu, Evan C. Reed +6
Dipole-phonon quantum logic (DPQL) leverages the interaction between polar molecular ions and the motional modes of a trapped-ion Coulomb crystal to provide a potentially scalable…
Reaction blockading in charged-neutral excited-state chemistry at low collision energy
Prateek Puri, Michael Mills, Ionel Simbotin +5
We study an excited atom-polar molecular ion chemical reaction (Ca + BaCl) at low temperature by utilizing a hybrid atom-ion trapping system. The reaction rate and product…
Excitation-assisted nonadiabatic charge-transfer reaction in a mixed atom-ion system
Ming Li, Michael Mills, Prateek Puri +3
An important physical process unique to neutral-ion systems is the charge-transfer (CT) reaction. Here, we present measurements of and models for CT processes between co-trapped ul…
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…
