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.
