Generalized Einstein Relation in an aging colloidal glass
Bérengère Abou, François Gallet, Pascal Monceau +1
We present an experimental and theoretical investigation of the Generalized Einstein Relation (GER), a particular form of a fluctuation-dissipation relation, in an out-of-equilibri…

Probing an nonequilibrium Einstein relation in an aging colloidal glass
Bérengère Abou, Francois Gallet
We present a direct experimental measurement of an effective temperature in a colloidal glass of Laponite, using a micrometric bead as a thermometer. The nonequilibrium fluctuation…

Nonlinear rheology of Laponite suspensions under an external drive
Bérengère Abou, Daniel Bonn, Jacques Meunier
We investigate the nonlinear rheological behavior of colloidal suspensions of Laponite, a synthetic clay, driven by a steady and homogeneous shear strain. We show that the external…
