I talk about our recent measurement of stochastic entropy production and of records of negative entropy. The system under study is a metallic double dot under a constant external DC bias which realizes Markovian nonequilibrium steady states.
We find that the cumulative distribution of entropy production is bounded at all times by a limiting exponential distribution with a mean value equal to minus the Boltzmann constant. We also derive an upper bound for the average maximal entropy uptake by a mesoscopic system from its environment in a finite time and confirm this result with experimental data.
