摘要

The Trajectory Class Fluctuation Theorem (TCFT) presents equalities between 熱力學 quantities, such as work costs and free energy changes, and the probabilities of classes of system-state trajectories in equilibrium-steady-state nonequilibrium processes. Conceptually, the TCFT unifies a host of previously-established fluctuation theorems, interpolating from Crooks' Detailed Fluctuation Theorem (single trajectories) to Jarzynski's Equality (full trajectory ensembles). Leveraging coarse-grained 資訊 about how systems evolve, the TCFT provides a substantial strengthening of the Second Law of 熱力學s-that, in point of fact, can be a rather weak bound between requisite work and free energy change. It also can be used to improve empirical estimates of free energies, a task known to be 統計ly challenging,
