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 ...

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 ...

Understanding an instability in vibrated granular monolayers
(American Physical Society, 2019)
We investigate the dynamics of an ensemble of smooth inelastic hard spheres confined between two horizontal plates separated by a distance smaller than twice the diameter of the particles, in such a way that the system is ...

Kinetic theory of a confined quasi-one-dimensional gas of hard disks
(Elsevier, 2022)
A dilute gas of hard disks confined between two straight parallel lines is considered. The distance between the two boundaries is between one and two particle diameters, so that the system is quasi-one-dimensional. A ...

Stability analysis of the homogeneous hydrodynamics of a model for a confined granular gas
(American Physical Society, 2016)
The linear hydrodynamic stability of a model for confined quasi-two-dimensional granular gases is analyzed. The system exhibits homogeneous hydrodynamics, i.e., there are macroscopic evolution equations for homogeneous ...

Rheological effects in the linear response and spontaneous fluctuations of a sheared granular gas
(American Physical Society, 2012)
The decay of a small homogeneous perturbation in the temperature of a dilute granular gas in the steady uniform shear flow state is investigated. Using kinetic theory based on the inelastic Boltzmann equation, a ...

Homogeneous hydrodynamics of a collisional model of confined granular gases
(American Physical Society, 2014)
The hydrodynamic equation governing the homogeneous time evolution of the temperature in a model of confined granular gas is studied by means of the Enskog equation. The existence of a normal solution of the kinetic equation ...

Mesoscopic theory of critical fluctuations in isolated granular gases
(American Physical Review, 2006-05-12)
Fluctuating hydrodynamics is used to describe the total energy fluctuations of a freely evolving gas of inelastic hard spheres near the threshold of the clustering instability. They are shown to be governed only by vorticity ...
