Shaking-induced crystallization of dense sphere packings
D. P. Shinde, Anita Mehta, G. C. Barker
We use a hybrid Monte Carlo algorithm to simulate the shaking of spheres at different vibrational amplitudes, and find that spontaneous crystallisation occurs in specific dynamical…
Bridges in three-dimensional granular packings: experiments and simulations
Yixin Cao, Bandan Chakrabortty, G. C. Barker +2
In this letter, we present the first experimental study of bridge structures in three-dimensional dry granular packings. When bridges are small, they are predominantly 'linear', an…
Finding bridges in packings of colloidal spheres
Matthew C. Jenkins, Mark D. Haw, Gary C. Barker +2
We identify putative load-bearing structures (bridges) in experimental colloidal systems studied by confocal microscopy. Bridges are co-operative structures that have been used to…
Competition and cooperation:aspects of dynamics in sandpiles
Anita Mehta, J M Luck, J M Berg +1
In this article, we review some of our approaches to granular dynamics, now well known to consist of both fast and slow relaxational processes. In the first case, grains typically…
Cooperativity in sandpiles: statistics of bridge geometries
Anita Mehta, G. C. Barker, J. M. Luck
Bridges form dynamically in granular media as a result of spatiotemporal inhomogeneities. We classify bridges as linear and complex, and analyse their geometrical characteristics.…
Inhomogeneous relaxation in vibrated granular media: consolidation waves
G. C. Barker, Anita Mehta
We investigate the spatial dependence of the density of vibrated granular beds, using simulations based on a hybrid Monte Carlo algorithm. We find that the initial consolidation is…
