【 摘 要 】

The Jarzynski equality relates nonequilibrium thermodynamics and equilibrium states. We realize a coupled quantum dot-electron reservoir system in which the time resolved observation of the tunneling dynamics is used to explicitly measure the exerted work and dissipated heat per single charge. We determine accurate values of the equilibrium free energy change over a large range of final state energies by driving the system far from equilibrium.
