Chaotic Rydberg atoms with broken time-reversal symmetry
Krzysztof Sacha, Jakub Zakrzewski, Dominique Delande
The dynamics of Rydberg states of atomic hydrogen perturbed simultaneously by a static electric field and a resonant microwave field of elliptical polarization is analysed in the q…
Resonant dynamics of the H atom in an elliptically polarized microwave field
Krzysztof Sacha, Jakub Zakrzewski
The dynamics of Rydberg states of atomic hydrogen driven by elliptically polarized microwaves of frequency fulfilling 2:1 classical resonance condition is investigated both semicla…
H atom in elliptically polarized microwaves: Semiclassical versus quantum resonant dynamics
Krzysztof Sacha, Jakub Zakrzewski
The dynamics of Rydberg states of atomic hydrogen illuminated by resonant elliptically polarized microwaves is investigated both semiclassically and quantum mechanically in a simpl…
Ionization via Chaos Assisted Tunneling
Jakub Zakrzewski, Dominique Delande, Andreas Buchleitner
A simple example of quantum transport in a classically chaotic system is studied. It consists in a single state lying on a regular island (a stable primary resonance island) which…
Nonuniversality in level dynamics
Paweł Kunstman, Karol Życzkowski, Jakub Zakrzewski
Statistical properties of parametric motion in ensembles of Hermitian banded random matrices are studied. We analyze the distribution of level velocities and level curvatures as we…
Statistical properties of random scattering matrices
Petr Seba, Karol Zyczkowski, Jakub Zakrzewski
We discuss the properties of eigenphases of S--matrices in random models simulating classically chaotic scattering. The energy dependence of the eigenphases is investigated and the…
