A consequence of local equilibration and heterogeneity in glassy materials | | Ludovic Berthier
; | | Date: |
21 Mar 2003 | | Journal: | J. Phys. A 36, 10667 (2003) | | Subject: | Statistical Mechanics; Disordered Systems and Neural Networks | cond-mat.stat-mech cond-mat.dis-nn | | Abstract: | The existence of a generalized fluctuation-dissipation theorem observed in simulations and experiments performed in various glassy materials is related to the concepts of local equilibration and heterogeneity in space. Assuming the existence of a dynamic coherence length scale up to which the system is locally equilibrated, we extend previous generalizations of the FDT relating static to dynamic quantities to the physically relevant domain where asymptotic limits of large times and sizes are not reached. The formulation relies on a simple scaling argument and has thus not the character of a theorem. Extensive numerical simulations support this proposition. Our results quite generally apply to systems with slow dynamics, independently of the space dimensionality, the chosen dynamics, or the presence of disorder. | | Source: | arXiv, cond-mat/0303453 | | Services: | Forum | Review | PDF | Favorites | |
