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…

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…

The Entropy Anomaly and the Linear Irreversible Thermodynamics
Kunimasa Miyazaki, Yohei Nakayama, Hiromichi Matsuyama
The irreversible currents and entropy production rate of a dilute colloidal suspension are calculated using the linear irreversible thermodynamics and the linear response theory. T…
