Weak localization of the open kicked rotator
arXiv:cond-mat/0405122 · doi:10.1103/PhysRevB.70.205324
Abstract
We present a numerical calculation of the weak localization peak in the magnetoconductance for a stroboscopic model of a chaotic quantum dot. The magnitude of the peak is close to the universal prediction of random-matrix theory. The width depends on the classical dynamics, but this dependence can be accounted for by a single parameter: the level curvature around zero magnetic field of the closed system.
