Experimental study of out of equilibrium fluctuations in a colloidal suspension of Laponite using optical traps
Pierre Jop, J. Ruben Gomez-Solano, Artyom Petrosyan +1
This work is devoted to the study of displacement fluctuations of micron-sized particles in an aging colloidal glass. We address the issue of the validity of the fluctuation dissip…
Probability density functions of work and heat near the stochastic resonance of a colloidal particle
Alberto Imparato, Pierre Jop, Artyom Petrosyan +1
We study experimentally and theoretically the probability density functions of the injected and dissipated energy in a system of a colloidal particle trapped in a double well poten…
Effective Temperature in a Colloidal Glass
Pierre Jop, Artyom Petrosyan, Sergio Ciliberto
We study the Brownian motion of particles trapped by optical tweezers inside a colloidal glass (Laponite) during the sol-gel transition. We use two methods based on passive rheolog…
Experimental evidence of non-Gaussian fluctuations near a critical point
Sylvain Joubaud, Artem Petrosyan, Sergio Ciliberto +1
The orientation fluctuations of the director of a liquid crystal are measured, by a sensitive polarization interferometer, close to the Fréedericksz transition, which is a second o…
