A universal ionization threshold for strongly driven Rydberg states
Andreas Krug, Andreas Buchleitner
We observe a universal ionization threshold for microwave driven one-electron Rydberg states of H, Li, Na, and Rb, in an {\em ab initio} numerical treatment without adjustable para…
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…
Decay Rates and Survival Probabilities in Open Quantum Systems
Sandro Wimberger, Andreas Krug, Andreas Buchleitner
We provide the first statistical analysis of the decay rates of strongly driven 3D atomic Rydberg states. The distribution of the rates exhibits universal features due to Anderson…
Residual Symmetries in the Spectrum of Periodically Driven Alkali Rydberg States
Andreas Krug, Andreas Buchleitner
We identify a fundamental structure in the spectrum of microwave driven alkali Rydberg states, which highlights the remnants of the Coulomb symmetry in the presence of a non-hydrog…
