Electronic properties of the Radium-monochalcogenides RaX (X = O,S,Se) and RaO+/- ions
Mateo Londoño, Jesús Pérez-RÃos
We present a theoretical investigation on the electronic structure and properties of radium monochalcogenides, with chalcogens O, S, and Se, as well as the ionic species RaO +/-. O…
AlF-AlF sticking time and prospects for ultracold dimers
Mahmoud A. E. Ibrahim, Mateo Londoño, Jesús Pérez-RÃos
We report on the sticking time of the AlF dimer in the ultracold regime. We employ a full-dimensional potential energy surface for AlF-AlF, constructed using a machine learning app…
What is the diatomic molecule with the largest dipole moment?
Ahmed Elhalawani, Ruiren Shi, Mateo Londoño Castellanos +2
We present a machine learning model for predicting the electric dipole moment of diatomic molecules using only the atomic properties of the constituent atoms. Our model can screen…
Rotational quenching of monofluorides in a cryogenic helium bath
Mateo Londoño, Jesús Pérez-RÃos
Buffer gas cooling, one of the most relevant direct cooling techniques for cooling molecules, relies on dissipating the energy of the molecule via collisions with a buffer gas. The…
Ultracold long-range van der Waals Rydberg trimer
Mateo Londoño, Vanessa C. Olaya-Agudelo, Felipe Herrera +1
Rydberg molecules, Rydberg-atom or Rydberg-molecule, are an essential ingredient of cold molecular sciences. However, due to the richness of Rydberg-neutral interactions, new kinds…
