Attosecond time-scale multi-electron collisions in the Coulomb four-body problem: traces in classical probability densities
Agapi Emmanouilidou, Jan Michael Rost
In the triple ionization of the Li ground state by single photon absorption the three electrons escape to the continuum mainly through two collision sequences with individual colli…
Optimal Stochastic Enhancement of Photoionization
Kamal P. Singh, Jan M. Rost
The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schrödinger equation. A modest amount…
Multipole expansions and Fock symmetry of the Hydrogen atom
A. V. Meremianin, J-M. Rost
The main difficulty in utilizing the O(4) symmetry of the Hydrogen atom in practical calculations is the dependence of the Fock stereographic projection on energy. This is due to t…
Antiblockade in Rydberg excitation of an ultracold lattice gas
Cenap Ates, Thomas Pohl, Thomas Pattard +1
It is shown that the two-step excitation scheme typically used to create an ultracold Rydberg gas can be described with an effective two-level rate equation, greatly reducing the c…
The Coulomb four-body problem in a classical framework: Triple photoionization of lithium
Agapi Emmanouilidou, Jan M. Rost
Formulating a quasiclassical approach we determine the cross section for the complete four-body break-up of the lithium ground state following single photon absorption from thresho…
