Distribution of entropy production for a colloidal particle in a nonequilibrium steady state
Distribution of entropy production for a colloidal particle in a nonequilibrium steady state
For a colloidal particle driven by a constant force across a periodic potential, we investigate the distribution of entropy production both experimentally and theoretically. For short trajectories, the fluctuation theorem holds experimentally. The mean entropy production rate shows two regimes as a function of the applied force. Theoretically, both mean …
