Mapping atomic trapping in an optical superlattice onto the libration of a planar rotor in electric fields
Marjan Mirahmadi, Bretislav Friedrich, Burkhard Schmidt +1
We show that two seemingly unrelated problems - the trapping of an atom in an optical superlattice (OSL) and the libration of a planar rigid rotor in combined electric and optical…
Trap-assisted complexes in cold atom-ion collisions
H. Hirzler, E. Trimby, R. Gerritsma +2
We theoretically investigate the trap-assisted formation of complexes in atom-ion collisions and their impact on the stability of the trapped ion. The time-dependent potential of t…
Hyperradial distribution function of few-body problems: a new arena for extreme value theory
Yu Wang, Marjan Mirahmadi, Ahmed A. Elkamshishy +1
This work explores classical capture models for few-body systems via a Monte Carlo method in hyperspherical coordinates. In particular, we focus on van der Waals and charged-induce…
The Molecular Migdal Effect
Carlos Blanco, Ian Harris, Yonatan Kahn +2
Nuclear scattering events with large momentum transfer in atomic, molecular, or solid-state systems may result in electronic excitations. In the context of atomic scattering by dar…
Barrier height prediction by machine learning correction of semiempirical calculations
Xabier García-Andrade, Pablo García Tahoces, Jesús Pérez-Ríos +1
Different machine learning (ML) models are proposed in the present work to predict DFT-quality barrier heights (BHs) from semiempirical quantum-mechanical (SQM) calculations. The M…
Ion-atom-atom three-body recombination in cold hydrogen and deuterium plasmas
Miruna T. Cretu, Marjan Mirahmadi, Jesús Pérez-Ríos
We present a detailed study about ion-atom-atom three-body recombination in hydrogen and deuterium plasmas based on classical trajectory calculations in hyperspherical coordinates.…
Dynamics of translational and rotational thermalization of AlF molecules via collisions with cryogenic helium
Mallikarjun Karra, Miruna T. Cretu, Bretislav Friedrich +3
We investigated helium-mediated translational and rotational thermalization of the aluminum monofluoride (AlF) molecule at cryogenic temperatures via a new potential…
Observation of Chemical Reactions between a Trapped Ion and Ultracold Feshbach Dimers
H. Hirzler, R. S. Lous, E. Trimby +3
We measure chemical reactions between a single trapped Yb ion immersed in an ultracold bath of Li atoms containing trace amounts of Li dimers. This produces LiY…
