چکیده

We study the counterpart of Anderson localization in driven one-electron Rydberg atoms. By changing the initial Rydberg state at fixed microwave frequency and interaction time, we numerically monitor the crossover from Anderson localization to the photoeffect in the atomic ionization signal.

A universal ionization threshold for strongly driven Rydberg states

The suppression of quantum transport across disordered media is one of the most spectacular consequences of destructive quantum interference. Originally predicted by Anderson [1] in his treatment of electrons propagating in disordered one dimensional lattices, Anderson localization has now become a general concept which prevails in abundant scenarios of coherent quantum transport in the presenc...

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...

How simple atoms mimic disorder

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 across disordered 1D lattices. Our results open a new arena for Anderson localization – a disorder induced effect – in a large class of perfectly deterministic, decaying atomic systems. PACS. 32.80.Rm Multiphoton ioniz...

Chaos-assisted tunneling in the presence of Anderson localization.

Tunneling between two classically disconnected regular regions can be strongly affected by the presence of a chaotic sea in between. This phenomenon, known as chaos-assisted tunneling, gives rise to large fluctuations of the tunneling rate. Here we study chaos-assisted tunneling in the presence of Anderson localization effects in the chaotic sea. Our results show that the standard tunneling rat...

Magnetic-field-driven localization of light in a cold-atom gas.

We discover a transition from extended to localized quasimodes for light in a gas of immobile two-level atoms in a magnetic field. The transition takes place either upon increasing the number density of atoms in a strong field or upon increasing the field at a high enough density. It has many characteristic features of a disorder-driven (Anderson) transition but is strongly influenced by near-f...
