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…

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…
