Dynamical stabilization of classical multi electron targets against autoionization
Tihamer Geyer, Jan M Rost
We demonstrate that a recently published quasiclassical M\oller type approach [Geyer and Rost 2002, J. Phys. B 35 1479] can be used to overcome the problem of autoionization, which…
Decay, interference, and chaos: How simple atoms mimic disorder
Andreas Krug, Sandro Wimberger, Andreas Buchleitner
We establish a close quantitative analogy between the excitation and ionization process of highly excited one electron Rydberg states under microwave driving and charge transport a…
Coherent backscattering of light by cold atoms: theory meets experiment
Guillaume Labeyrie, Dominique Delande, Cord A. Mueller +2
Coherent backscattering (CBS) of quasi-resonant light by cold atoms presents some specific features due to the internal structure of the atomic scatterers. We present the first qua…
Nondispersive two-electron wave packets in driven helium
Peter Schlagheck, Andreas Buchleitner
We provide a detailed quantum treatment of the spectral characteristics and of the dynamics of nondispersive two-electron wave packets along the periodically driven, collinear froz…
High-order above-threshold ionization: the uniform approximation and the effect of the binding potential
C. Figueira de Morisson Faria, H. Schomerus, W. Becker
A versatile semiclassical approximation for intense laser-atom processes is presented. This uniform approximation is no more complicated than the frequently-used multi-dimensional…
QED theory of transition probabilities and line profiles in highly-charged ions
L. N. Labzowsky, A. Prosorov, A. V. Shonin +3
A rigorous QED theory of the spectral line profiles is applied to transition probabilities in few-electron highly charged ions. Interelectron interaction corrections are included a…
