Local fluctuations in an aging glass
arXiv:cond-mat/0412378 · doi:10.1103/PhysRevLett.95.067205
Abstract
Polarization fluctuations were measured in nanoscale volumes of a polymer glass during aging following a temperature quench through the glass transition. Statistical properties of the noise were studied in equilibrium and during aging. The noise spectral density had a larger temporal variance during aging, i.e. the noise was more non-Gaussian, demonstrating stronger correlations during aging.
