Energy dissipation and violation of the fluctuation-response relation in non-equilibrium Langevin systems
Takahiro Harada, Shin-ichi Sasa
The fluctuation-response relation is a fundamental relation that is applicable to systems near equilibrium. On the other hand, when a system is driven far from equilibrium, this re…
Microscopic description of the equality between violation of fluctuation-dissipation relation and energy dissipation
Hiroshi Teramoto, Shin-ichi Sasa
In systems far from equilibrium, the fluctuation-dissipation relation is violated due to the lack of detailed balance. Recently, for a class of Langevin equations, it has been prov…
The law of action and reaction for the effective force in a nonequilibrium colloidal system
Kumiko Hayashi, Shin-ichi Sasa
We study a nonequilibrium Langevin many-body system containing two 'test' particles and many 'background' particles. The test particles are spatially confined by a harmonic potenti…
Computation of the Kolmogorov-Sinai entropy using statistitical mechanics: Application of an exchange Monte Carlo method
Shin-ichi Sasa, Kumiko Hayashi
We propose a method for computing the Kolmogorov-Sinai (KS) entropy of chaotic systems. In this method, the KS entropy is expressed as a statistical average over the canonical ense…
Linear response theory in stochastic many-body systems revisited
Kumiko Hayashi, Shin-ichi Sasa
The Green-Kubo relation, the Einstein relation, and the fluctuation-response relation are representative universal relations among measurable quantities that are valid in the linea…
Equality connecting energy dissipation with violation of fluctuation-response relation
Takahiro Harada, Shin-ichi Sasa
In systems driven away from equilibrium, the velocity correlation function and the linear response function to a small perturbation force do not satisfy the fluctuation-response re…
