| Outline of Final Research Achievements |
We aimed to construct steady state thermodynamics, which may be applicable to various nano-machines such as proteins driven by chemical reactions. We have successfully derived an inequality corresponding to the second law of thermodynamics for non-equilibrium systems. The obtained inequality forms the combination of the minimum work principle and the linear response relation, both of which are milestones of equilibrium thermodynamics and non-equilibrium physics, respectively. As a first application of the inequality, we demonstrated the relation of equilibrium pumping to the mechanical work in driven states. According to this relation, we are possible to get experimental data for the pumping from the mechanical operation to the subjects under a conjugate driving.
