Geometry-controlled phase transition in vibrated granular media
René Zuñiga, Germán Varas, Stéphane Job
We report experiments on the dynamics of vibrated particles constrained in a two-dimensional vertical container, motivated by the following question: how to get the most out of a g…
Dynamics of crater formations in immersed granular materials
Germán Varas, Valérie Vidal, Jean-Christophe Géminard
We report the formation of a crater at the free surface of an immersed granular bed,locally crossed by an ascending gas flow. In two dimensions, the crater consists of two piles wh…
Collective behavior in a granular jet: Emergence of a liquid with zero surface-tension
Xiang Cheng, German Varas, Daniel Citron +2
We perform the analog to the "water bell" experiment using non-cohesive granular material. When a jet of granular material, many particles wide, rebounds from a fixed cylindrical t…
