Two-dimensional melting far from equilibrium in a granular monolayer
J. S. Olafsen, J. S. Urbach
We report an experimental investigation of the transition from a hexagonally ordered solid phase to a disordered liquid in a monolayer of vibrated spheres. The transition occurs as…
Anisotropic dynamics in a shaken granular dimer gas experiment
J. Atwell, J. S. Olafsen
The dynamics, velocity fluctuations, and particle-plate interactions for a 2D granular gas of shaken, non-spherical particles are studied experimentally. The experiment consists of…
Coarsening of granular clusters: two types of scaling behaviors
M. V. Sapozhnikov, I. S. Aranson, J. S. Olafsen
We report on an experimental study of small cluster dynamics during the coarsening process in driven granular submonolayers of 120mkm bronze particles. The techniques of electrosta…
Velocity Fluctuations in Electrostatically Driven Granular Media
I. S. Aranson, J. S. Olafsen
We study experimentally the particle velocity fluctuations in an electrostatically driven dilute granular gas. The experimentally obtained velocity distribution functions have stro…
