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…
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…
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…
Quantum-limited thermometry of a Fermi gas with a charged spin particle
Lorenzo Oghittu, Antonio Negretti
We investigate the sensitivity of an ion sensor in determining the temperature of an atomic Fermi gas. Our study extends to charged impurities the proposal by M. T. Mitchison et al…
