Classical, Semiclassical and Quantum Dynamics in Atoms

可憎

,Semiclassical floquet spectra without periodic orbits from ħ-expansion of floquet matrix, here extend the analysis to the next-to-leading order in ħ for the Floquet matrix. The accuracy for the quasienergy spectrum improves accordingly. Moreover, we thus explain why the previous leading-order treatment gave the mentioned 3% accuracy.

Ionization of hydrogen atoms by circularly polarized microwaves,em reveals similarities and, sometimes, strong differences between the two systems. Both are of value for deepening the understanding of the nature of the ionization process as well as, more generally, of quantum systems which classically exhibit irregular or mixed regular-irregular behaviour.

Two-electron atoms: From resonances to fragmentation,he two-electron system from the ground state across the complete fragmentation threshold into the two-electron continuum. We will illustrate the results for the helium atom, electron-hydrogen and electron-helium scattering.

Randy L. Bell,Tyler L. St.Claironding classical system. Various regimes of the two point correlation function, from the ballistic chaotic regime to the diffusive one, are explored and characterized. The derivation of the relation between . and the Perron-Frobenius operator, which was obtained in the framework of the supersymmetric σ-model, is outlined.
