The disordering caused by mechanical or thermal agitation is represented by atomic volume dilatation and used as an order par...<br/>[Phys. Rev. B 80, 104201] Published Wed Sep 23, 2009 G. P.

Kolton, and Leticia F. Cugliandolo<br/>We study the thermally assisted relaxation of a directed elastic line in a two-dimensional quenched random potential by solving numerically the Edwards-Wilkinson equation and the Monte Carlo dynamics of a solid-on-solid lattice model. We show that the aging dynamics is governed by a growing correlat...<br/>[Phys. Rev. B 80, 094201] Published Wed Sep 09, 2009 José Luis Iguain, Sebastian Bustingorry, Alejandro B.
