Memory effects in a gas of viscoelastic particles
E. Mompó, M. A. López-Castaño, A. Torrente +2
We study a granular gas of viscoelastic particles (kinetic energy loss upon collision is a function of the particles' relative velocities at impact) subject to a stochastic thermos…

Induced correlations and rupture of molecular chaos by anisotropic dissipative Janus hard disks
Antonio Lasanta, Aurora Torrente, Mariano Lopez de Haro
A system of smooth "frozen" Janus-type disks is studied. Such disks cannot rotate and are divided by their diameter into two sides of different inelasticities. Taking as a referenc…

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…
