Off equilibrium fluctuations in a polymer glass
L. Buisson, S. Ciliberto
The fluctuation-dissipation relation (FDR) is measured on the dielectric properties a polymer glass (polycarbonate). It is observed that the fluctuation dissipation theorem is stro…
A Simple Denoising Technique
F. Douarche, L. Buisson, S. Ciliberto +1
The measurements of very low level signals at low frequency is a very difficult problem, because environmental noise increases in this frequency domain and it is very difficult to…
Electrical noise properties in aging materials
L. Buisson, M. Ciccotti, L. Bellon +1
The electric thermal noise has been measured in two aging materials, a colloidal suspension (Laponite) and a polymer (polycarbonate), presenting very slow relaxation towards equili…
Intermittent origin of the large violations of the fluctuation dissipation relations in an aging polymer glass
L. Buisson, S. Ciliberto, A. Garcimartin
The fluctuation-dissipation relation (FDR) is measured on the dielectric properties of a polymer glass (polycarbonate)in the range . It is found that after a quench…
