Semiclassical Theory of Quantum Chaotic Transport: Phase-Space Splitting

TL;DR

This paper discusses semiclassical theory in quantum chaotic transport, highlighting an exponential suppression of weak localization at finite Ehrenfest time, with some earlier comments now considered obsolete.

Contribution

It revises previous claims by demonstrating exponential suppression of weak localization in the deep semiclassical limit.

Findings

Weak localization corrections are exponentially suppressed at finite Ehrenfest time.

Some earlier comments on weak localization are now obsolete.

Main findings remain valid despite the paper's withdrawal.

Abstract

This paper is withdrawn. While almost all findings reported here remain valid, some of our comments on the fate of weak localization corrections to the conductance in the deep semiclassical limit are now obsolete. Contrarily to what was suggested here, we find an exponential suppression of weak localization at finite Ehrenfest time. For more details, see cond-mat/0512662 .
