Breakdown of hydrodynamics in the inelastic Maxwell model of granular gases
(American Physical Society, 2010)
Both the right and left eigenfunctions and eigenvalues of the linearized homogeneous Boltzmann equation for inelastic Maxwell molecules corresponding to the hydrodynamic modes are calculated. Also, some nonhydrodynamic ...

Slow logarithmic relaxation in models with hierarchically constrained dynamics
(American Physical Society, 2001)
A general kind of model with hierarchically constrained dynamics is shown to exhibit logarithmic anomalous relaxation similar to a variety of complex strongly interacting materials. The logarithmic behavior describes most ...

Homogeneous cooling state of a low-density granular flow
(American Physical Society, 1996)
The homogeneous cooling state of a granular flow of smooth spherical particles described by the Boltzmann equation is investigated by means of the direct simulation Monte Carlo method. The velocity moments and also the ...

Self-diffusion in a quasi-two-dimensional gas of hard spheres
(American Physical Society, 2020)
A quasi-two-dimensional system of hard spheres strongly confined between two parallel plates is considered. The attention is focused on the macroscopic self-diffusion process observed when the system is seen from above or ...

Internal energy fluctuations of a granular gas under steady uniform shear flow
(American Physical Society, 2012)
The stochastic properties of the total internal energy of a dilute granular gas in the steady uniform shear flow state are investigated. A recent theory formulated for fluctuations about the homogeneous cooling state is ...

Origin of density clustering in a freely evolving granular gas
(American Physical Society, 1999)
The physical mechanisms leading to the development of density inhomogeneities in a freely evolving low density granular gas are investigated. By means of the direct simulation Monte Carlo method, numerical solutions of the ...

Boundary conditions and normal state for a vibrated granular fluid
(American Physical Society, 2000)
The steady state of a fluidized granular system confined between a vibrating wall and a reflecting one is analyzed in detail. The relationship between the velocity of the wall and the hydrodynamic profiles is established. ...

Analysis of nonlinear transport in Couette flow
(American Physical Society, 1989)
The nonlinear Bhatnagar, Gross, and Krook [Phys. Rev. 94, 511 (1954)] kinetic equation is solved for boundary conditions leading to planar Couette flow and heat transport. In the limit of zero Knudsen number but arbitrary ...
