Microscopic origin of granular ratcheting
S. McNamara, R. García-Rojo, H. J. Herrmann
Numerical simulations of assemblies of grains under cyclic loading exhibit ``granular ratcheting'': a small net deformation occurs with each cycle, leading to a linear accumulation…

Symmetry breaking and clustering in a vibrated granular gas with several macroscopically connected compartments
J. Javier Brey, R. Garcia-Rojo, F. Moreno +1
The spontaneous symmetry breaking in a vibro-fluidized low-density granular gas in three connected compartments is investigated. When the total number of particles in the system be…

Indeterminacy, Memory, and Motion in a Simple Granular Packing
S. McNamara, R. Rojo-Garcia, H. J. Herrmann
We apply two theoretical and two numerical methods to the problem of a disk placed in a groove and subjected to gravity and a torque. Methods assuming rigid particles are indetermi…
