Low density fragile states in cohesive powders
Paul B. Umbanhowar, Daniel I. Goldman
We discuss the difference between cohesive and non-cohesive granular media in the context of a recent report of "dry quicksand." Weak low density states with properties like dry qu…
Signatures of glass formation in a fluidized bed of hard spheres
Daniel I. Goldman, Harry L. Swinney
We demonstrate that a fluidized bed of hard spheres during defluidization displays properties associated with formation of a glass. The final state is rate dependent, and as this s…
Stationary state volume fluctuations in a granular medium
Matthias Schröter, Daniel I. Goldman, Harry L. Swinney
A statistical description of static granular material requires ergodic sampling of the phase space spanned by the different configurations of the particles. We periodically fluidiz…
