Scattering Faddeev calculations in the double continuum
Romain Guérout
We use the configuration-space Faddeev formalism to study scattering of three particles in the double continuum where all particles are free. All scattering processes, starting fro…
Quasi-resonant van der Waals interaction between non-identical atoms
Manuel Donaire, Romain Guérout, Astrid Lambrecht
We present a time-dependent quantum calculation of the van der Waals interaction between a pair of dissimilar atoms, one of which is initially excited while the other one is in its…
Liouville transformations and quantum reflection
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +1
Liouville transformations of Schrödinger equations preserve the scattering amplitudes while changing the effective potential. We discuss the properties of these gauge transformatio…
Structure of the Alkali-metal-atom-Strontium molecular ions: towards photoassociation and formation of cold molecular ions
Mireille Aymar, Romain Guérout, Olivier Dulieu
The potential energy curves, permanent and transition dipole moments, and the static dipolar polarizability, of molecular ions composed of one alkali-metal atom and a Strontium ion…
Casimir-Polder interaction between an atom and a dielectric grating
Ana M. Contreras-Reyes, Romain Guérout, Paulo A. Maia Neto +3
We develop the scattering approach to calculate the exact dispersive Casimir-Polder potential between a ground-state atom and a rectangular grating. Our formalism allows, in princi…
Electronic structure of the Magnesium hydride molecular ion
Mireille Aymar, Romain Guérout, Mohamed Sahlaoui +1
In this paper, using a standard quantum chemistry approach based on pseudopotentials for atomic core representation, Gaussian basis sets, and effective core polarization potentials…
