Reversibility in nonequilibrium trajectories of an optically trapped particle

Reid, James; Carberry, David; Wang, Genmiao; Sevick, Edith M; Evans, Denis; Searles, Debra


The measure of irreversibility as the dissipation function that serves as the quantitative argument in the fluctuation theorem (FT) was investigated. The FT describes the system's thermodynamic irreversibility developed in time from a completely thermodynamically reversibble system at short times to a thermodynamically irreversible one at infinitely long times. It was observed that the ensemble average of ωt was positive definite irrespective of the system for which it was constructed. It was...[Show more]
