Ratchet effect in the quantum kicked rotor and its destruction by dynamical localization
Ratchet effect in the quantum kicked rotor and its destruction by dynamical localization
We study experimentally a quantum kicked rotor with broken parity symmetry, supporting a ratchet effect due to the presence of a classical accelerator mode. We show that the short-time dynamics is very well described by the classical dynamics, characterized by a strongly asymmetric momentum distribution with directed motion on one …
