Exact equalities and thermodynamic relations for nonequilibrium steady states
Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa +1
We study thermodynamic operations which bring a nonequilibrium steady state (NESS) to another NESS in physical systems under nonequilibrium conditions. We model the system by a sui…
A glimpse of fluid turbulence from the molecular scale
Teruhisa S. Komatsu, Shigenori Matsumoto, Takashi Shimada +1
Large scale molecular dynamics simulations of freely decaying turbulence in three-dimensional space are reported. Fluid components are defined from the microscopic states by elimin…
Entropy and Nonlinear Nonequilibrium Thermodynamic Relation for Heat Conducting Steady States
Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa +1
Among various possible routes to extend entropy and thermodynamics to nonequilibrium steady states (NESS), we take the one which is guided by operational thermodynamics and the Cla…
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…
