Diffusion and velocity correlations of the phase transitions in a system of macroscopic rolling spheres
F. Vega Reyes, A. Rodríguez-Rivas, J. F. González-Saavedra +1
We study an air-fluidized granular monolayer, composed of plastic spheres which roll on a metallic grid. The air current is adjusted so that the spheres never loose contact with th…
Diffusive regimes in a two-dimensional chiral fluid
Francisco Vega Reyes, Miguel A. López-Castaño, Álvaro Rodríguez-Rivas
Diffusion is a fundamental aspect of transport processes in biological systems, and thus, in the development of life itself. And yet, the diffusive dynamics of active fluids with d…
Energy nonequipartition in gas mixtures of inelastic rough hard spheres: The tracer limit
Francisco Vega Reyes, Antonio Lasanta, Andrés Santos +1
The dynamical properties of a tracer or impurity particle immersed in a host gas of inelastic and rough hard spheres in the homogeneous cooling state is studied. Specifically, the…
Inherent thermal convection in a gas inside a box under a gravity field
F. Vega Reyes, A. Puglisi, G. Pontuale +1
We theoretically prove the existence in granular fluids of a thermal convection that is inherent, in the sense that is always present and has no thermal gradient threshold (convect…
When the Hotter Cools More Quickly: Mpemba Effect in Granular Fluids
Antonio Lasanta, Francisco Vega Reyes, Antonio Prados +1
Under certain conditions, two samples of fluid at different initial temperatures present a counterintuitive behavior known as the Mpemba effect: it is the hotter system that cools…
