Experimental measurements of the fluctuations of the work W given to
and the heat Q dissipated by an harmonic oscillator in contact with a thermostat,
together with an analytical derivation of the the probability density function of W and Q.
Fluctuation Theorems for those two quantities are studied :
arXiv preprint of a full report on fluctuations of W and Q,
with a formulation of the first principle, the study of transient evolutions and steady
states (with a linear or sinusoidal time-prescription of the driving), and the definition
of the distance from equilibrium.
arXiv preprint Fluctuations in a resistor :
Fluctuation Dissipation Theorem (FDT) and Fluctuation Theorems (FT) for work and heat
have been tested on a model electrical system.
arXiv preprint presenting a novel
method (from Pierre Gaspard)
to measure entropy production from time series, and how this has been exploited on our experimental data.
arXiv preprint presenting experimental measurements
of extreme fluctuations of large negative amplitude in two turbulent flows, and how those
fluctuations verify the Fluctuation Theorem.
