The Jarzynski equality
So our latest little obsession in research-land is something called The Jarzynski Equality, which is a strong statement about equilibrium thermodynamical quantities being exactly derivable from irreversible (non-equilibrium) trajectories. Jarzynski has a brief commentary in PNAS that describes it, but … Continue reading
