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…
Explicit schemes for time propagating many-body wavefunctions
Ana Laura Frapiccini, Aliou Hamido, Sebastian Schröter +6
Accurate theoretical data on many time-dependent processes in atomic and molecular physics and in chemistry require the direct numerical solution of the time-dependent Schrödinger…
Interaction of atomic quantum gases with a single carbon nanotube
Martin Fink, Tim-Oliver Müller, Johannes Eiglsperger +1
We study inelastic processes in the hybrid quantum system constituted by a carbon nanotube (CNT) in contact with an ultracold quantum gas, such as a cloud of thermal atoms or a Bos…
Time scaling with efficient time-propagation techniques for atoms and molecules in pulsed radiation fields
Aliou Hamido, Johannes Eiglsperger, Javier Madroñero +4
We present an ab initio approach to solve the time-dependent Schrödinger equation to treat electron and photon impact multiple ionization of atoms or molecules. It combines the alr…
Spectral data for doubly excited states of helium with non-zero total angular momentum
Johannes Eiglsperger, Moritz Schönwetter, Bernard Piraux +1
A spectral approach is used to evaluate energies and widths for a wide range of singlet and triplet resonance states of helium. Data for total angular momentum is prese…
Ericson fluctuations in an open, deterministic quantum system: theory meets experiment
J. Madronero, A. Buchleitner
We provide numerically exact photoexcitation cross sections of rubidium Rydberg states in crossed, static electric and magnetic fields, in quantitative agreement with recent experi…
