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…
Intruders in disguise: Mimicry effect in granular gases
Antonio Lasanta, Francisco Vega Reyes, Vicente Garzó +1
In general, the total kinetic energy in a multicomponent granular gas of inelastic and rough hard spheres is unequally partitioned among the different degrees of freedom. On the ot…
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…
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…
Hydrodynamics of a Granular Gas in a Heterogeneous Environment
Francisco Vega Reyes, Antonio Lasanta
We analyze the transport properties of a low density ensemble of identical macroscopic particles immersed in an active fluid. The particles are modeled as inelastic hard spheres (g…
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…
Thermal properties of an impurity immersed in a granular gas of rough hard spheres
Francisco Vega Reyes, Antonio Lasanta, Andrés Santos +1
We study in this work the dynamics of a granular impurity immersed in a low-density granular gas of identical particles. For description of the kinetics of the granular gas and the…
Unified rheology of vibro-fluidized dry granular media: From slow dense flows to fast gas-like regimes
Andrea Gnoli, Antonio Lasanta, Alessandro Sarracino +1
Granular media take on great importance in industry and geophysics, posing a severe challenge to materials science. Their response properties elude known soft rheological models, e…
Lattice models for granular-like velocity fields: Hydrodynamic limit
Alessandro Manacorda, Carlos A. Plata, Antonio Lasanta +2
A recently introduced model describing -on a 1d lattice- the velocity field of a granular fluid is discussed in detail. The dynamics of the velocity field occurs through next-neigh…
An Itinerant Oscillator model with cage inertia for mesorheological granular experiments
A. Lasanta, A. Puglisi
Recent experiments with a rotating probe immersed in weakly fluidized granular materials show a complex behavior on a wide range of timescales. Viscous-like relaxation at high freq…
Statistics of the dissipated energy in driven diffusive systems
A. Lasanta, Pablo I. Hurtado, A. Prados
Understanding the physics of non-equilibrium systems remains as one of the major open questions in statistical physics. This problem can be partially handled by investigating macro…
