Topological effects in ring polymers (II): Influence of persistence length
M. Muller, J. P. Wittmer, M. E. Cates
The interplay of topological constraints and persistence length of ring polymers in their own melt is investigated by means of dynamical Monte Carlo simulations of a three dimensio…
Stress Propagation in Sand
M. E. Cates, J. P. Wittmer
We describe a new continuum approach to the modelling of stress propagation in static granular media, focussing on the conical sandpile created from a point source. We argue that t…
Topological effects in ring polymers: A computer simulation study
M. Mueller, J. P. Wittmer, M. E. Cates
Unconcatenated, unknotted polymer rings in the melt are subject to strong interactions with neighboring chains due to the presence of topological constraints. We study this by comp…
Diffusive growth of a polymer layer by in sity polymerization
J. P. Wittmer, M. E. Cates, A. Johner +1
We consider the growth of a polymer layer on a flat surface in a good solvent by in-situ polymerization. This is viewed as a modified form of diffusion-limited aggregation without…
Development of Stresses in Cohesionless Poured Sand
M. E. Cates, J. Wittmer, J. P. Bouchaud +1
The pressure distribution beneath a conical sandpile, created by pouring sand from a point source onto a rough rigid support, shows a pronounced minimum below the apex (`the dip').…
Shear-Induced Clustering in a Simple Driven Diffusive Model
O. J. O'Loan, M. R. Evans, M. E. Cates
We study a simple lattice model of shear-induced clustering in two dimensions in which clusters of particles aggregate under an imposed shear flow and fragment stochastically. Two…
