Brownian motor in a granular medium
Riccardo Balzan, Fergal Dalton, Vittorio Loreto +2
In this work we experimentally study the behavior of a freely-rotating asymmetric probe immersed in a vibrated granular medium. For a wide variety of vibration conditions the probe…
What is the temperature of a granular medium?
A. Baldassarri, A. Barrat, G. D'Anna +3
In this paper we discuss whether thermodynamical concepts and in particular the notion of temperature could be relevant for the dynamics of granular systems. We briefly review how…
Extreme events driven glassy behaviour in granular media
G. D'Anna, P. Mayor, G. Gremaud +2
Motivated by recent experiments on the approach to jamming of a weakly forced granular medium using an immersed torsion oscillator [Nature 413 (2001) 407], we propose a simple mode…
Fluctuation-Dissipation relations in Driven Granular Gases
A. Puglisi, A. Baldassarri, V. Loreto
We study the dynamics of a 2d driven inelastic gas, by means of Direct Simulation Monte Carlo (DSMC) techniques, i.e. under the assumption of Molecular Chaos. Under the effect of a…
Coarsening and Slow-Dynamics in Granular Compaction
A. Baldassarri, S. Krishnamurthy, V. Loreto +1
We address the problem of the microscopic reorganization of a granular medium under a compaction process in the framework of Tetris-like models. We point out the existence of regio…
Memory in aged granular media
A. Barrat, V. Loreto
Stimulated by recent experimental results, we simulate ``temperature''-cycling experiments in a model for the compaction of granular media. We report on the existence of two types…
