Extracting partial decay rates of helium from complex rotation: autoionizing resonances of the one-dimensional configurations
Klaus Zimmermann, Pierre Lugan, Felix Jörder +5
Partial autoionization rates of doubly excited one-dimensional helium in the collinear Zee and eZe configuration are obtained by means of the complex rotation method. The approach…
Interaction effects on dynamical localization in driven helium
Felix Jörder, Klaus Zimmermann, Alberto Rodriguez +1
Dynamical localization prevents driven atomic systems from fast fragmentation by hampering the excitation process. We present numerical simulations within a collinear model of micr…
Diagrammatic approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
Vyacheslav Shatokhin, Thomas Wellens, Andreas Buchleitner
We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduc…
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…
Quantum Accelerator Modes from the Farey Tree
A. Buchleitner, M. B. d'Arcy, S. Fishman +5
We show that mode-locking finds a purely quantum non-dissipative counterpart in atom-optical quantum accelerator modes. These modes are formed by exposing cold atoms to periodic ki…
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…
