Unifying renormalized and bare viscosity in two-dimensional molecular dynamics simulations
Kazuma Yokota, Masato Itami, Shin-ichi Sasa
Fluctuating hydrodynamics provides a framework connecting mesoscopic fluctuations with macroscopic transport behavior. To bridge mesoscopic and macroscopic transport from microscop…
Anomalous fluctuations of renewal-reward processes with heavy-tailed distributions
Hiroshi Horii, Raphael Lefevere, Masato Itami +1
For renewal-reward processes with a power-law decaying waiting time distribution, anomalously large probabilities are assigned to atypical values of the asymptotic processes. Previ…
Effective Langevin equations leading to large deviation function of time-averaged velocity for a nonequilibrium Rayleigh piston
Masato Itami, Yohei Nakayama, Naoko Nakagawa +1
We study fluctuating dynamics of a freely movable piston that separates an infinite cylinder into two regions filled with ideal gas particles at the same pressure but different tem…
Stochastic order parameter dynamics for phase coexistence in heat conduction
Shin-ichi Sasa, Naoko Nakagawa, Masato Itami +1
We propose a stochastic order parameter equation for describing phase coexistence in steady heat conduction near equilibrium. By analyzing the stochastic dynamics with a non-equili…
Multiplicative Langevin Equation to Reproduce Long-time Properties of Nonequilibrium Brownian Motion
Atsumasa Seya, Tatsuya Aoyagi, Masato Itami +2
We statistically examine long time sequences of Brownian motion for a nonequilibrium version of the Rayleigh piston model and confirm that the third cumulant of a long-time displac…
Singular behaviour of time-averaged stress fluctuations on surfaces
Masato Itami, Shin-ichi Sasa
We provide a method for calculating time-averaged stress fluctuations on surfaces in a viscous incompressible fluid at equilibrium. We assume that (i) the time-averaged fluctuating…
Universal Form of Stochastic Evolution for Slow Variables in Equilibrium Systems
Masato Itami, Shin-ichi Sasa
Nonlinear, multiplicative Langevin equations for a complete set of slow variables in equilibrium systems are generally derived on the basis of the separation of time scales. The fo…
Derivation of Stokes' Law from Kirkwood's Formula and the Green-Kubo Formula via Large Deviation Theory
Masato Itami, Shin-ichi Sasa
We study the friction coefficient of a macroscopic sphere in a viscous fluid at low Reynolds number. First, Kirkwood's formula for the friction coefficient is reviewed on the basis…
Nonequilibrium Statistical Mechanics for Adiabatic Piston Problem
Masato Itami, Shin-ichi Sasa
We consider the dynamics of a freely movable wall of mass with one degree of freedom that separates a long tube into two regions, each of which is filled with rarefied gas part…
Macroscopically measurable force induced by temperature discontinuities at solid-gas interfaces
Masato Itami, Shin-ichi Sasa
We consider a freely movable solid that separates a long tube into two regions, each of which is filled with a dilute gas. The gases in each region are initially prepared at the sa…
