Fidelity of the quantum delta-kicked accelerator
arXiv:1210.5656 · doi:10.1103/PhysRevE.87.020902
Abstract
The sensitivity of the fidelity in the kicked rotor to an acceleration is experimentally and theoretically investigated. We used a Bose-Einstein condensate exposed to a sequence of pulses from a standing light wave followed by a single reversal pulse in which the standing wave was shifted by half a wavelength. The features of the fidelity "spectrum" as a function of acceleration are presented. This work may find application in the measurement of temperature of an atomic sample.
