Mode-dependent nonequilibrium temperature in aging systems

Abstract: We introduce an exactly solvable model for glassy dynamics with many relaxational modes, each one characterized by a different relaxational time scale. Analytical solution of the aging dynamics at low temperatures shows that a nonequilibrium or effective temperature can be associated to each time scale or mode. The spectrum of effective temperatures shows two regions that are separated by an age-dependent boundary threshold. Region I is characterized by partially equilibrated modes that relax faster than the m… Show more

“…Such models have been widely used for the realistic modelling of structural ( Fig. 20) and electronic properties of tetrahedral amorphous networks [211,213,214], and these simple interaction potentials have been also used to investigate the glass transition phenomenology [215,216,217,218]. A certain number of salient features can be recovered within a Metropolis dynamics (see next subsection).…”

“…The success of mean-field theory to qualitatively reproduce most of the observed phenomenology in glasses suggests that NEAS are determined by the relaxation of mean-field like regions, maybe the largest CRRs in the system. Based on this analogy several mean-field based phenomenological approaches have been proposed [153,154,155,156,157].…”
