Unifying different interpretations of the nonlinear response in glass-forming liquids
P. Gadige, S. Albert, M. Mich +8
This work aims at reconsidering several interpretations coexisting in the recent literature concerning non-linear susceptibilities in supercooled liquids. We present experimental r…
Fifth-order susceptibility unveils growth of thermodynamic amorphous order in glass-formers
S. Albert, Th. Bauer, M. Michl +7
Glasses are ubiquitous in daily life and technology. However the microscopic mechanisms generating this state of matter remain subject to debate: Glasses are considered either as m…
Resistance Noise Scaling in a Dilute Two-Dimensional Hole System in GaAs
R. Leturcq, D. L'Hote, R. Tourbot +2
We have measured the resistance noise of a two-dimensional (2D)hole system in a high mobility GaAs quantum well, around the 2D metal-insulator transition (MIT) at zero magnetic fie…
Status of the EDELWEISS Experiment
L. Berge, I. Berkes, B. Chambon +20
The status of the EDELWEISS experiment (underground dark matter search with heat-ionisation bolometers) is reviewed. Auspicious results achieved with a prototype 70 g Ge heat-ionis…
A method for measuring the nonlinear response in dielectric spectroscopy through third harmonics detection
C. Thibierge, D. L'Hote, F. Ladieu +1
We present a high sensitivity method allowing the measurement of the non linear dielectric susceptibility of an insulating material at finite frequency. It has been developped for…
Non-ohmic hopping transport in a-YSi: from isotropic to directed percolation
F. Ladieu, D. L'Hôte, R. Tourbot
Variable range hopping transport has been investigated in amorphous YSi from 30 mK to 2 K as a function of the temperature T and electric field F. For F=0, where conduction is alon…
