Query: Non-equilibrium work distribution for interacting colloidal particles
  under friction   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 several parameters which can influence the
shape of the work distribution, e.g. the number of particles used to locally
probe the system and the time interval to measure the work. We find that, when
tuning the control parameters to induce particle depinning from the substrate,
there is an abrupt change of the shape of the work distribution. While in the
completely static and sliding friction regimes the work distribution is
Gaussian, non-Gaussian tails show up due to the spatiotemporal heterogeneity of
the particle dynamics during the transition between these two regimes.
