Fluctuation theorems for an asymmetric rotor in a granular gas
Sylvain Joubaud, Detlef Lohse, Devaraj Van Der Meer
We investigate the validity of fluctuation theorems for an asymmetric rotor experiment in a granular gas. A first state, with a Gaussian distribution of the angular velocity, is fo…
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…
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…
Fluctuations of the total entropy production in stochastic systems
Sylvain Joubaud, Nicolas Garnier, Sergio Ciliberto
Fluctuations of the excess heat in an out of equilibrium steady state are experimentally investigated in two stochastic systems : an electric circuit with an imposed mean current a…
Experimental study of work fluctuations in a harmonic oscillator
Sylvain Joubaud, Nicolas Garnier, Frédéric Douarche +2
The work fluctuations of a harmonic oscillator in contact with a thermostat and driven out of equilibrium by an external force are studied experimentally. For the work both the tra…
Entropy production and time asymmetry in nonequilibrium fluctuations
David Andrieux, Pierre Gaspard, Sergio Ciliberto +3
The time-reversal symmetry of nonequilibrium fluctuations is experimentally investigated in two out-of-equilibrium systems namely, a Brownian particle in a trap moving at constant…
