| dc.description | This paper was withdrawn by the authors. The purpose of this paper was to provide conclusive evidence for the Ehrenfest-time-independence of weak localization, by means of a computer simulation of the coherent backscattering peak on very large systems. (Two orders of magnitude larger than we could reach in cond-mat/0405122 by studying weak localization directly.) We have decided to withdraw this paper, after Piet Brouwer convinced us that the one-to-one correspondence between weak localization and coherent backscattering can not be relied upon. For example, a reflection matrix with one half of its eigenvalues equal to 0 and the other half equal to 1 (hence without weak localization) would still show a coherent backscattering peak in a basis that is randomly related to its eigenbasis. | |
