Ehrenfest time in the weak dynamical localization
Abstract
The quantum kicked rotor (QKR) is known to exhibit dynamical localization in the space of its angular momentum. The present paper is devoted to the systematic first-principles (without a regularizer) diagrammatic calculations of the weak-localization corrections for the QKR. Our particular emphasis is on the Ehrenfest time regime—the phenomena characteristic for the classical-to-quantum crossover of classically chaotic systems.
