Confinement-induced resonances for the creation of quasi-one-dimensional ultra cold gases of alkali--alkaline-earth dimers
Lorenzo Oghittu, Premjith Thekkeppatt, Nirav P. Mehta +4
We theoretically investigate the role of confinement-induced resonances (CIRs) in low-dimensional ultracold atomic mixtures for the formation of weakly bound dimers. To this end, w…

Ultracold collisions of a neutral atom with a trapped ion in 1D
Seth T. Rittenhouse, Lorenzo Oghittu, Arghavan Safavi-Naini +2
We present a fully quantum mechanical description of a free Li atom scattering from a trapped Yb ion in one dimension. By reformulating the system in polar coordina…

Phonon-mediated quantum gates in trapped ions coupled to an ultracold atomic gas
Lorenzo Oghittu, Arghavan Safavi-Naini, Antonio Negretti +1
We study the dynamics of phonon-mediated qubit-qubit interactions between trapped ions in the presence of an ultracold atomic gas. By deriving and solving a master equation to desc…
