Intermittent origin of the large violations of the fluctuation dissipation relations in an aging polymer glass [PDF]
, 2003 The fluctuation-dissipation relation (FDR) is measured on the dielectric properties of a polymer glass (polycarbonate)in the range $20mHz - 100Hz$. It is found that after a quench below the glass transition temperature the fluctuation dissipation theorem
