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…
Estimate of the free energy difference in mechanical systems from work fluctuations: experiments and models
Frederic Douarche, Sergio Ciliberto, Artem Petrosyan
The work fluctuations of an oscillator in contact with a heat reservoir and driven out of equilibrium by an external force are studied experimentally. The oscillator dynamics is mo…
