Non-Gaussian distributions under scrutiny
Thierry Dauxois
Comment of the very interesting paper by Hilhorst & Schehr, J. Stat. Mech. P06003 (2007). The main point is that one should be extremely careful when interpreting non-Gaussian data…
Thermodynamic time asymmetry in nonequilibrium fluctuations
David Andrieux, Sergio Ciliberto, Nicolas Garnier +3
We here present the complete analysis of experiments on driven Brownian motion and electric noise in a circuit, showing that thermodynamic entropy production can be related to…
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…
A Three Dimensional Kasteleyn Transition: Spin Ice in a [100] Field
Ludovic D. C. Jaubert, J. T. Chalker, Peter C. W. Holdsworth +1
We examine the statistical mechanics of spin-ice materials with a [100] magnetic field. We show that the approach to saturated magnetisation is, in the low-temperature limit, an ex…
Fluctuation theorems for harmonic oscillators
Sylvain Joubaud, Nicolas Garnier, Sergio Ciliberto
We study experimentally the thermal fluctuations of energy input and dissipation in a harmonic oscillator driven out of equilibrium, and search for Fluctuation Relations. We study…
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…
