Laser-assisted binding of ultracold polar molecules with Rydberg atoms in the van der Waals regime
Vanessa Olaya, Jesús Pérez-Ríos, Felipe Herrera
We study ultracold long-range collisions of heteronuclear alkali-metal dimers with a reservoir gas of alkali-metal Rydberg atoms in a two-photon laser excitation scheme. In a low d…
Is CCSD(T) a proper standard for dipole moment calculations? An analysis considering diverse diatomic species
Xiangyue Liu, Laura McKemmish, Jesús Pérez-Ríos
Coupled cluster with single, double, and perturbative triple excitations [CCSD(T)] has been extensively employed as the reference method in benchmarking different quantum chemistry…
Electric field dissociation of weakly bound molecular ions
Jesús Pérez-Ríos
We present a full quantal study on the dissociation of a weakly bound molecular ion in the presence of an external time-dependent electric field. We focus on the dissociation dynam…
Rydberg atom-ion collisions in cold environments
Henrik Hirzler, Jesús Pérez-Ríos
Low-energy collisions of Rydberg atom-ion systems are investigated theoretically. We present the parameter space associated with suitable approaches for the dynamics of Rydberg ato…
On the universality of spectroscopic constants of diatomic molecules
Xiangyue Liu, Gerard Meijer, Jesús Pérez-Ríos
We show, through a machine learning approach, that the equilibrium distance, harmonic vibrational frequency, and binding energy of diatomic molecules are universally related. In pa…
Controlling the nature of a charged impurity in a bath of Feshbach dimers
Henrik Hirzler, Eleanor Trimby, Rianne S. Lous +3
We theoretically study the dynamics of a trapped ion that is immersed in an ultracold gas of weakly bound atomic dimers created by a Feshbach resonance. Using quasi-classical simul…
