Spontaneous spirals in vibrated granular chains
R. E. Ecke, Z. A. Daya, M. K. Rivera +1
We present experimental measurements on the spontaneous formation of compact spiral structures in vertically-vibrated granular chains. Under weak vibration, when the chain is quasi…

Knots and Random Walks in Vibrated Granular Chains
E. Ben-Naim, Z. A. Daya, P. Vorobieff +1
We study experimentally statistical properties of the opening times of knots in vertically vibrated granular chains. Our measurements are in good qualitative and quantitative agree…

Dynamics of Vibrated Granular Monolayers
X. Nie, E. Ben-Naim, S. Y. Chen
We study statistical properties of vibrated granular monolayers using molecular dynamics simulations. We show that at high excitation strengths, the system is in a gas state, parti…
