Order and Chaos in the One-Dimensional Model : N-Dependence and the Second Law of Thermodynamics
William Graham Hoover, Kenichiro Aoki
We revisit the equilibrium one-dimensional model from the dynamical systems point of view. We find an infinite number of periodic orbits which are computationally stable. At…
Distributional Behavior of Diffusion Coefficients Obtained by Single Trajectories in Annealed Transit Time Model
Takuma Akimoto, Eiji Yamamoto
Local diffusion coefficients in disordered systems such as spin glass systems and living cells are highly heterogeneous and may change over time. Such a time-dependent and spatiall…
One-body reduced density matrix of trapped impenetrable anyons in one dimension
Giacomo Marmorini, Michele Pepe, Pasquale Calabrese
We study the one-body reduced density matrix of a system of one-dimensional impenetrable anyons trapped by a harmonic potential. To this purpose we extend two methods developed…
Universal trade-off relation between power and efficiency for heat engines
Naoto Shiraishi, Keiji Saito, Hal Tasaki
For a general thermodynamic system described as a Markov process, we prove a general lower bound for dissipation in terms of the square of the heat current, thus establishing that…
Langevin equation with fluctuating diffusivity: a two-state model
Tomoshige Miyaguchi, Takuma Akimoto, Eiji Yamamoto
Recently, anomalous subdiffusion, aging, and scatter of the diffusion coefficient have been reported in many single-particle-tracking experiments, though origins of these behaviors…
Universal Fluctuations of Single-Particle Diffusivity in Quenched Environment
Takuma Akimoto, Eli Barkai, Keiji Saito
Local diffusion coefficients in disordered materials such as living cells are highly heterogeneous. Quenched disorder is utilized substantially to study such complex systems, where…
Distributional Behaviors of Time-averaged Observables in Langevin Equation with Fluctuating Diffusivity: Normal Diffusion but Anomalous Fluctuations
Takuma Akimoto, Eiji Yamamoto
We consider Langevin equation with dichotomously fluctuating diffusivity, where the diffusion coefficient changes dichotomously in time, in order to study fluctuations of time-aver…
