The pseudo-two-dimensional dynamics in a system of macroscopic rolling spheres
M. A. López-Castaño, J. F. González-Saavedra, A. Rodríguez-Rivas +3
We study in this work the dynamics of a collection of identical hollow spheres (ping-pong balls) that rest on a horizontal metallic grid. Fluidization is achieved by means of a tur…

Zero-gravity thermal convection in granular gases
Álvaro Rodríguez-Rivas, Miguel A. López-Castaño, Francisco Vega Reyes
Previous experimental and theoretical evidence has shown that convective flow may appear in granular fluids if subjected to a thermal gradient and gravity (Rayleigh-Bénard-type con…

Large Mpemba-like effect in a gas of inelastic rough hard spheres
Aurora Torrente, Miguel A. López-Castaño, Antonio Lasanta +3
We report the emergence of a giant Mpemba effect in the uniformly heated gas of inelastic rough hard spheres: The initially hotter sample may cool sooner than the colder one, even…
