Hamiltonian derivation of a detailed fluctuation theorem

摘要

We analyze the microscopic evolution of a system undergoing afar-from-equilibrium thermodynamic process. Explicitly accounting for thedegrees of freedom of participating heat reservoirs, we derive a hybrid result,similar in form to both the fluctuation theorem, and a statement of detailedbalance. We relate this result to the steady-state fluctuation theorem, and toa free energy relation valid far from equilibrium.
