Kicked rotor is a paradigmatic model for classical and quantum chaos in time-dependent
Hamiltonian systems. More than fifty years since the introduction of this model, there is an …

We report the first direct experimental realization of the quantum δ-kicked rotor. Our system
consists of a dilute sample of ultracold sodium atoms in a periodic standing wave of near …

During recent years we could bear witness to an immense research activity, both in
experimental and theoretical physics, as well as in chemistry, aimed at understanding the …

We report on the experimental observation of environment induced decoherence in the
quantum delta-kicked rotor. Ultracold cesium atoms are subjected to a pulsed standing wave …

This paper reviews the physics of quantum disorder in relation with a series of experiments
using laser-cooled atoms exposed to “kicks” of a standing wave, realizing a paradigmatic …

We observe the effects of noise and dissipation on dynamical localization. Our system
consists of cold cesium atoms in a pulsed standing wave of light, and is an experimental …

We study the band-random-matrix model for conservative Hamiltonian systems, originally
proposed by Wigner in 1955. On the basis of numerical data we show that both the global …

We report the experimental observation of rectified momentum transport for a Bose-Einstein
condensate kicked at the Talbot time (quantum resonance) by an optical standing wave …

This paper presents the first experimental evidence of the transition from dynamical
localization to delocalization under the influence of a quasiperiodic driving on a quantum …

Operators in ergodic spin chains are found to grow according to hydrodynamical equations
of motion. The study of such operator spreading has aided our understanding of many-body …
