Representation of nonequilibrium steady states in large mechanical systems
Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa +1
Recently a novel concise representation of the probability distribution of heat conducting nonequilibrium steady states was derived. The representation is valid to the second order…
Steady State Thermodynamics for Heat Conduction -- Microscopic Derivation
Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa +1
Starting from microscopic mechanics, we derive thermodynamic relations for heat conducting nonequilibrium steady states. The extended Clausius relation enables one to experimentall…
An expression for stationary distribution in nonequilibrium steady state
Teruhisa S. Komatsu, Naoko Nakagawa
We study the nonequilibrium steady state realized in a general stochastic system attached to multiple heat baths and/or driven by an external force. Starting from the detailed fluc…
A heat pump at a molecular scale controlled by a mechanical force
Naoko Nakagawa, Teruhisa S. Komatsu
We show that a mesoscopic system such as Feynman's ratchet may operate as a heat pump, and clarify a underlying physical picture. We consider a system of a particle moving along an…
Hidden heat transfer in equilibrium states implies directed motion in nonequilibrium states
Teruhisa S. Komatsu, Naoko Nakagawa
We study a class of heat engines including Feynman's ratchet, which exhibits a directed motion of a particle in nonequilibrium steady states maintained by two heat baths. We measur…
An oriented process induced by dynamically regulated energy barriers
Naoko Nakagawa, Teruhisa S. Komatsu
A novel mechanism for the appearance of oriented processes is investigated with a flexible dynamical system overcoming barriers. Under non-equilibrium condition with external drivi…
