Geometric frustration induces the transition between rotation and counterrotation in swirled granular media
Experiments and numerical simulations of swirled granular media and identification of the minimal ingredients for the particles and their interactions necessary to induce counterrotation.
Swirling granular matter: From rotation to reptation
Experiments and numerical simulations of granular material under swirling motion of the container.
Swirling granular solidlike clusters
Experiments and three-dimensional numerical simulations are presented to elucidate the dynamics of granular material in a cylindrical dish driven by a horizontal, periodic motion. (Following publication to "Swirling granular matter: From rotation to reptation")
The rotation-reptation transition under broken rotational symmetry
Experimentally investigation of the transitions between rotational to reptational mode (and "snake mode") under the influence of geometrical distortions which break the rotational symmetry of the container. The driving mechanism for the rotational motion of the clusters is also discussed.
