Second law and Landauer principle far from equilibrium
  The amount of work that is needed to change the state of a system in contact with a heat bath between specified initial and final nonequilibrium states is at least equal to the corresponding equilibrium free energy difference plus (resp. minus) temperature times the information of the final (resp. the initial) state relative to the corresponding equilibrium distributions.
