Calculation of displacement correlation tensor indicating vortical cooperative motion in two-dimensional colloidal liquids
T. Ooshida, S. Goto, T. Matsumoto +1
As an indicator of cooperative motion in a system of Brownian particles that models two-dimensional colloidal liquids, displacement correlation tensor is calculated analytically an…
Nonequilibrium identities and response theory for dissipative particles
Hisao Hayakawa, Michio Otsuki
We derive some nonequilibrium identities such as the integral fluctuation theorem and the Jarzynski equality starting from a nonequilibrium state for dissipative classical systems.…
Analytical Calculation of Four-Point Correlations for a Simple Model of Cages Involving Numerous Particles
T. Ooshida, S. Goto, T. Matsumoto +2
Dynamics of a one-dimensional system of Brownian particles with short-range repulsive interaction (diameter sigma) is studied with a liquid-theoretical approach. The mean square di…
Constitutive Relations of Jammed Frictionless Granular Materials under Oscillatory Shear
Michio Otsuki, Hisao Hayakawa
We numerically investigate the rheological properties of jammed frictionless granular materials under an oscillatory shear in terms of our simulation of the distinct element method…
Rheology of sheared granular particles near jamming transition
Michio Otsuki, Hisao Hayakawa
We investigate the rheology of sheared granular materials near the jamming transition point. We numerically determine the values of the critical fraction and the exponents for the…
Critical scaling of jammed system after quench of temperature
Michio Otsuki, Hisao Hayakawa
Critical behavior of soft repulsive particles after quench of temperature near the jamming trasition is numerically investigated. It is found that the plateau of the mean square di…
