Abstract: The local flow rule and the cooperativity length are the crucial ingredients of non-local rheology of granular matter. Once they are known as functions of the stress ratio, one can predict steady-state flow in arbitrarily… read more here.

DOI: 10.1103/physreve.105.024903
Abstract: We study the behavior of cylindrical objects as they sink into a dry granular bed fluidized due to lateral oscillations. Somewhat unexpectedly, we have found that, within a large range of lateral shaking powers, cylinders… read more here.
