We investigated the validity of the fluctuation dissipation theorem in\ud
\ud
the structural glass former triphenylolmethane triglycidyl ether.\ud
\ud
Polarization relaxation measurements were compared to the thermal\ud
\ud
fluctuation of the polarization. We observed that above the glass\ud
\ud
transition temperature, the fluctuation dissipation theorem is fully\ud
\ud
verified, whereas below the glass transition temperature the power noise\ud
\ud
spectrum measured subsequently to a temperature quench is more intense\ud
\ud
than that expected from response measurements. The amplitude of the\ud
\ud
fluctuation is distributed according to a non Gaussian distribution,\ud
\ud
whose origin is not strictly related to the presence of intense noise\ud
\ud

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
