Steady state thermodynamics
Shin-ichi Sasa, Hal Tasaki
The present paper reports our attempt to search for a new universal framework in nonequilibrium physics. We propose a thermodynamic formalism that is expected to apply to a large c…
Anomalous time correlation in two-dimensional driven diffusive systems
Takenobu Nakamura, Michio Otsuki, Shin-ichi Sasa
We study the time correlation function of a density field in two-dimensional driven diffusive systems within the framework of fluctuating hydrodynamics. It is found that the time c…
Decomposition of force fluctuations far from equilibrium
Kumiko Hayashi, Shin-ichi Sasa
By studying a nonequilibrium Langevin system, we find that a simple condition determines the decomposition of the coarse-grained force into a dissipative force, an effective drivin…
Statistics of unstable periodic orbits of a chaotic dynamical system with a large number of degrees of freedom
Mitsuhiro Kawasaki, Shin-ichi Sasa
For a simple model of chaotic dynamical systems with a large number of degrees of freedom, we find that there is an ensemble of unstable periodic orbits (UPOs) with the special pro…
Long range spatial correlation between two Brownian particles under external driving
Shin-ichi Sasa
We study the large distance behavior of a steady distribution of two Brownian particles under external driving in a two-dimensional space. Employing a method of perturbative system…
Extended Einstein relations with a complex effective temperature in a one dimensional driven lattice gas
Kumiko Hayashi, Shin-ichi Sasa
We carried out numerical experiments on a one-dimensional driven lattice gas to elucidate the statistical properties of steady states far from equilibrium. By measuring the bulk de…
