Growing length scale in gravity-driven dense granular flow
Shubha Tewari, Bidita Tithi, Allison Ferguson +1
We report simulations of a two-dimensional, dense, bidisperse system of inelastic hard disks falling down a vertical tube under the influence of gravity. We examine the approach to…
Spatially heterogenous dynamics in dense, driven granular flows
Allison Ferguson, Bulbul Chakraborty
Interest in the dynamical arrest leading to a fluid --> solid transition in thermal and athermal systems has led to questions about the nature of these transitions. These jamming t…
Secondary Structures in Long Compact Polymers
Richard Oberdorf, Allison Ferguson, Jesper L. Jacobsen +1
Compact polymers are self-avoiding random walks which visit every site on a lattice. This polymer model is used widely for studying statistical problems inspired by protein folding…
Stress and large-scale spatial structures in dense, driven granular flows
Allison Ferguson, Bulbul Chakraborty
We study the appearance of large-scale dynamical heterogeneities in a simplified model of a driven, dissipative granular system. Simulations of steady-state gravity-driven flows of…
Impulse distributions in dense granular flows: signatures of large-scale spatial structures
A. Ferguson, B. Fisher, B. Chakraborty
In this paper we report the results of simulations of a 2D gravity driven, dissipative granular flow through a hopper system. Measurements of impulse distributions P(I) on the simu…
