Nonequilibrium dynamics in an amorphous solid
Abstract
The non-equilibrium dynamics of an amorphous solid is studied with a soft-spin type model. We show that the aging behavior in the glassy state follows a modified Kohlrausch-Williams-Watts (KWW) form similar to that obtained in Phys. Rev. Lett. 95, 055702 (2005) from analysis of the dielectric loss data. The nature of the fluctuation-dissipation theorem (FDT) violation is also studied in the time as well as correlation windows.
