Where the article explains it
where W is the work performed on the system along a single nonequilibrium trajectory, F is the equilibrium free-energy difference between the initial and final states, and is inverse temperature.
The passage around this formula
where W is the work performed on the system along a single nonequilibrium trajectory, F is the equilibrium free-energy difference between the initial and final states, and is inverse temperature. The average on the left is taken over repeated realizations of the same driving protocol, each of which can dissipate a different amount of work due to thermal fluctuations. The identity holds exactly regardless of how fast or far from equilibrium the driving protocol…
