Strong interaction effects in Σ- atoms

Large bandwidth excitation of Rydberg atoms in thermal vapor: Fast dynamics and strong interaction effects

SLIMP: Strong laser interaction model package for atoms and molecules

We present the SLIMP package, which provides an efficient way for the calculation of strong-field ionization rate and high-order harmonic spectra based on the single active electron approximation. The initial states are taken as single-particle orbitals directly fromoutput files of the general purpose quantumchemistry programs GAMESS, Firefly and Gaussian. For ionization, the molecular Ammosov–...

Strong Interaction Effects in Scalar Top Production

The search for supersymmetry is on the “to do” list of all experiments at currently operating or planned high energy particle colliders. It is commonly believed that hadron colliders are better suited for the search for strongly interacting sparticles (gluinos and squarks) than lepton colliders are. Hadron colliders indeed offer larger cross sections for producing such sparticles. However, expe...

Relativistic hydrogenic atoms in strong magnetic fields

In the Dirac operator framework we characterize and estimate the ground state energy of relativistic hydrogenic atoms in a constant magnetic field and describe the asymptotic regime corresponding to a large field strength using relativistic Landau levels. We also define and estimate a critical magnetic field beyond which stability is lost.

Breit interaction in heavy atoms

In this letter we discuss how to include Breit interaction in calculations of low-energy properties of heavy atoms in accurate and effective way. In order to illustrate our approach we give some results for Cs and Tl. Introduction. It is well known that in high accuracy atomic calculations one may need to go beyond the Coulomb approximation for the two-electron interaction. The usual next step ...
