Non-equilibrium work distribution for interacting colloidal particles under friction
2015
New Journal of Physics
We experimentally investigate the distribution of the non-equilibrium work done by an external force on a mesoscopic system with many coupled degrees of freedom: a colloidal monolayer mechanically driven across a periodic light field. Since this system mimics the spatiotemporal dynamics of a crystalline surface moving on a corrugated substrate, our results show general properties of the non-equilibrium work distribution of atomically flat surfaces undergoing friction. We address the role of
