Webquantum mechanical suppression of chaos exhibits strik-ing similarities to the phenomenon of Anderson localiza-tion in disordered metallic wires [1]. By deﬁnition, the kicked rotor is a point particle that moves freely on a circle. The particle is kicked periodi-cally in time, where the kick strength depends on the angular position. WebThe system under consideration is an atom optics δ-kicked rotor for which a fidelity based measurement has been proposed to possess a rapid scaling of sensitivity (N−3) with pulse number N. Although attractive, we demonstrate that this scaling does not hold in the regime where the momentum selectivity of the pulse sequence becomes significantly smaller … Webconsidering another system, the quantum kicked rotor (QKR). This system has been extensively studied in the framework of quantum chaos [34]. From an experimental point of view, it has allowed the study of interference effects mimicking those observed with spatial disorder in a very controlled way [35].

WebUnexpected accelerator modes were recently observed experimentally for cold cesium atoms when driven in the presence of gravity. A detailed theoretical explanation of this quantum effect is presented here. The theory makes use of invariance properties of the system, that are similar to the ones of solids, leading to a separation into independent … WebThe kicked rotator, also spelled as kicked rotor, is a prototype model for chaos and quantum chaos studies. It describes a particle that is constrained to move on a ring (equivalently: a rotating stick). The particle is kicked periodically by an homogeneous field (equivalently: the gravitation is switched on periodically in short pulses).
