Rydberg atomic antenna in strongly driven multielectron atoms

Magnetic trapping of strongly-magnetized Rydberg atoms

Effective magnetic moments of drift Rydberg atoms in strong magnetic fields are obtained for different energy and angular-momentum states. Classical two-body trajectory calculations and quantummechanical one-body calculations are employed. For heavy atoms such as rubidium, the trapping dynamics can largely be explained by the net magnetic moment due to the cyclotron and the magnetron motion of ...

Conductance fluctuations in microwave-driven Rydberg atoms

– We draw and quantitatively support a parallel between conductance fluctuations in one-dimensional disordered solids and fluctuations of lifetimes of hydrogen atoms in microwave fields. In particular, we numerically analyze the statistics of scaled atomic resonance widths in the localized regime and we find a lognormal distribution, quantitatively consistent with the theory of Anderson localiz...

Driven Rydberg atoms reveal quartic level repulsion.

The dynamics of Rydberg states of a hydrogen atom subjected simultaneously to uniform static electric field and two microwave fields with commensurate frequencies is considered in the range of small field amplitudes. In the certain range of the parameters of the system the classical secular motion of the electronic ellipse reveals chaotic behavior. Quantum mechanically, when the fine structure ...

Breaking time reversal symmetry in chaotic driven Rydberg atoms

We consider the dynamics of Rydberg states of the hydrogen atom driven by a microwave field of elliptical polarization, with a possible additional static electric field. We concentrate on the effect of a resonant weak field whose frequency is close to the Kepler frequency of the electron around the nucleus which essentially produces no ionization of the atom, but completely mixes the various st...
