Fluctuations, linear response and heat flux of an aging system
Juan Ruben Gomez-Solano, Artyom Petrosyan, Sergio Ciliberto
We measure the fluctuations of the position of a Brownian particle confined by an optical trap in an aging gelatin droplet after a fast quench. Its linear response to an external p…
Fluctuations in out of equilibrium systems: from theory to experiment
Sergio Ciliberto, Sylvain Joubaud, Artem Petrosyan
We introduce from an experimental point of view the main concepts of fluctuation theorems for work, heat and entropy production in out of equilibrium systems. We will discuss the i…
Steady state fluctuation relations for systems driven by an external random force
Juan Ruben Gomez-Solano, Ludovic Bellon, Artyom Petrosyan +1
We experimentally study the fluctuations of the work done by an external Gaussian random force on two different stochastic systems coupled to a thermal bath: a colloidal particle i…
Experimental verification of a modified fluctuation-dissipation relation for a micron-sized particle in a non-equilibrium steady state
Juan Ruben Gomez-Solano, Artyom Petrosyan, Sergio Ciliberto +2
A modified fluctuation-dissipation-theorem (MFDT) for a non-equilibrium steady state (NESS) is experimentally checked by studying the position fluctuations of a colloidal particle…
Work fluctuations in a nematic liquid crystal
Sylvain Joubaud, Guillaume Huillard, Artyom Petrosyan +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…
Aging and effective temperatures near a critical point
Sylvain Joubaud, Baptiste Percier, Artem Petrosyan +1
The orientation fluctuations of the director of a liquid crystal(LC) are measured after a quench near the Fréedericksz transition, which is a second order transition driven by an e…
