Aging and effective temperatures in the low temperature mode-coupling equations
arXiv:cond-mat/9611051 · doi:10.1143/PTPS.126.407
Abstract
The low-temperature generalization of the mode-coupling equations corresponds to the dynamics of mean-field disordered models in the glassy phase. The system never achieves equilibrium, preserving the memory of the time elapsed after the quench throughout its evolution. A concept of effective temperature can be made quite rigorous in this context by considering readings of thermometers in different time-scales and the thermalization of weakly coupled subsystems.
