Spectroscopic constants from atomic properties: a machine learning approach
Mahmoud A. E. Ibrahim, X. LiU, J. Pérez-Ríos
We present a machine-learning approach toward predicting spectroscopic constants based on atomic properties. After collecting spectroscopic information on diatomics and generating…
Molecular dynamics-driven global tetra-atomic potential energy surfaces: Application to the AlF dimer
Xiangyue Liu, Weiqi Wang, Jesús Pérez-Ríos
In this work, we present a general machine learning approach for full-dimensional potential energy surfaces for tetra-atomic systems. Our method employs an active learning scheme t…
Cold atom-ion systems in radiofrequency multipole traps: event-drive molecular dynamics and stochastic simulations
Mateo Londoño, Javier Madroñero, Jesús Pérez-Ríos
We have studied the general aspects of the dynamics of an ion trapped in an ideal multipolar radiofrequency trap while interacting with a dense cold atomic gas. In particular, we h…
Three-body recombination in physical chemistry
Marjan Mirahmadi, Jesús Pérez-Ríos
Three-body recombination, or ternary association, is a termolecular reaction in which three particles collide, forming a bound state between two, whereas the third escapes freely.…
PyQCAMS: Python Quasi-Classical Atom-Molecule Scattering
Rian Koots, Jesús Pérez-Ríos
We present Python Quasi-classical atom-molecule scattering (PyQCAMS), a new Python package for atom-molecule scattering within the quasi-classical trajectory approach. The input co…
Cold chemistry: a few-body perspective on impurity physics of a single ion in an ultracold bath
Jesús Pérez-Ríos
Impurity physics is a traditional topic in condensed matter physics that nowadays is being explored in the field of ultracold gases. Among the different classes of impurities, we f…
External field control of collective spin excitations in an optical lattice of molecules
Jesús Pérez-Ríos, Felipe Herrera, Roman V. Krems
We show that an ensemble of molecules in the rotationally ground state trapped on an optical lattice exhibits collective spin excitations that can be controlled by applying s…
