| Abstract: | The fluctuation-dissipation relation (FDR)is measured on the dielectric properties
of a polymer glass (polycarbonate)in the range 20 mHz–100Hz. It is found that after a
quench below the glass transition temperature, the fluctuation-dissipation theorem is strongly
violated. The amplitude and the persistence time of this violation are decreasing functions of
frequency. At frequencies larger than 1Hz it persists for about 3 h. The origin of this violation
is a highly intermittent dynamics characterized by large fluctuations. The relevance of these
results for recent models of aging dynamics is discussed. |
