Hamilton-Jacobi method for molecular distribution function in a chemical oscillator
Hiizu Nakanishi, Takahiro Sakaue, Jun'ichi Wakou
Using the Hamilton-Jacobi method, we solve chemical Fokker-Planck equations within the Gaussian approximation and obtain a simple and compact formula for a conditional probability…
Inelastic collapse in one-dimensional driven systems under gravity
Jun'ichi Wakou, Hiroyuki Kitagishi, Takahiro Sakaue +1
We study the inelastic collapse in the one-dimensional -particle systems in the situation where the system is driven from below under the gravity. We investigate the hard-sphere…
Fluctuation-Dissipation Relations for Motions of Center of Mass in Driven Granular Fluids under Gravity
Jun'ichi Wakou, Masaharu Isobe
We investigated the validity of fluctuation-dissipation relations in the nonequilibrium stationary state of fluidized granular media under gravity by two independent approaches, ba…
A New Approach based on Langevin type Equation for Driven Granular Gas under Gravity
Jun'ichi Wakou, Masaharu Isobe
We propose a novel approach based on a Langevin equation for fluctuating motion of the center of mass of granular media fluidized by energy injection from a bottom plate. In this f…
A Langevin Approach to One-Dimensional Granular Media Fluidized by Vibrations
Jun'ichi Wakou, Akinori Ochiai, Masaharu Isobe
We present a Langevin approach to describe the steady-state dynamics of one-dimensional granular media fluidized by a vibrating bottom plate. We adopt a linear Langevin equation to…
A Systematic Expansion Method in Granular Hydrodynamics
J. Wakou
We propose a systematic expansion method which is applied to freely evolving granular fluids contained in sufficiently small systems. Restricting ourselves to small systems, we sho…
Towards a Landau-Ginzburg-type Theory for Granular Fluids
J. Wakou, R. Brito, M. H. Ernst
In this paper we show how, under certain restrictions, the hydrodynamic equations for the freely evolving granular fluid fit within the framework of the time dependent Landau-Ginzb…
