Rotational transport via spontaneous symmetry breaking in vibrated disk packings
Cristian Fernando Moukarzel, Gonzalo Peraza-Mues, Osvaldo Carvente
It is shown that vibrated packings of frictional disks self-organize cooperatively onto a rotational-transport state where the long-time angular velocity of each disk …
Phase Transition in Liquid Drop Fragmentation
Cristian F. Moukarzel, Silvia F. Fernandez-Sabido, J. C. Ruiz-Suarez
A liquid droplet is fragmented by a sudden pressurized-gas blow, and the resulting droplets, adhered to the window of a flatbed scanner, are counted and sized by computerized means…
Fragmentation Experiment and Model for Falling Mercury Drops
P. M. C. de Oliveira, C. A. F. Leite, C. V. Chianca +2
The experiment consists of counting and measuring the size of the many fragments observed after the fall of a mercury drop on the floor. The size distribution follows a power-law f…
Rigidity percolation in a field
Cristian F. Moukarzel
Rigidity Percolation with g degrees of freedom per site is analyzed on randomly diluted Erdos-Renyi graphs with average connectivity gamma, in the presence of a field h. In the (ga…
Transport on percolation clusters with power-law distributed bond strengths: when do blobs matter?
Mikko Alava, Cristian Moukarzel
The simplest transport problem, namely maxflow, is investigated on critical percolation clusters in two and three dimensions, using a combination of extremal statistics arguments a…
Shortest paths on systems with power-law distributed long-range connections
Cristian F. Moukarzel, Marcio Argollo de Menezes
We discuss shortest-path lengths on periodic rings of size L supplemented with an average of pL randomly located long-range links whose lengths are distributed according…
Sliding blocks with random friction and absorbing random walks
A. R. Lima, Cristian F. Moukarzel, I. Grosse +1
With the purpose of explaining recent experimental findings, we study the distribution of distances traversed by a block that slides on an inclined plane and stops due t…
Directed rigidity and bootstrap percolation in (1+1) dimensions
Marcio Argollo de Menezes, Cristian F. Moukarzel
We study directed rigidity percolation (equivalent to directed bootstrap percolation) on three different lattices: square, triangular, and augmented triangular. The first two of th…
Floppy modes and the free energy: Rigidity and connectivity percolation on Bethe Lattices
P. M. Duxbury, D. J. Jacobs, M. F. Thorpe +1
We show that negative of the number of floppy modes behaves as a free energy for both connectivity and rigidity percolation, and we illustrate this result using Bethe lattices. The…
Reply to the comment by Jacobs and Thorpe
Phillip M. Duxbury, Cristian F. Moukarzel, Paul L. Leath
Reply to a comment on "Infinite-Cluster geometry in central-force networks", PRL 78 (1997), 1480. A discussion about the order of the rigidity percolation transition.
Comparison of connectivity and rigidity percolation
Cristian F. Moukarzel, Phillip M. Duxbury
We summarize ideas and methods that apply to rigidity and connectivity percolation. These include: constraint counting concepts, exact calculations on diluted trees and numerical r…
Isostatic phase transition and instability in stiff granular materials
Cristian F. Moukarzel
In this letter, structural rigidity concepts are used to understand the origin of instabilities in granular aggregates. It is shown that: a) The contact network of a noncohesive gr…
A fast algorithm for backbones
Cristian F. Moukarzel
A matching algorithm for the identification of backbones in percolation problems is introduced. Using this procedure, percolation backbones are studied in two- to five-dimensional…
Comparison of rigidity and connectivity percolation in two dimensions
Cristian F. Moukarzel, Phillip M. Duxbury
Using a recently developed algorithm for generic rigidity of two-dimensional graphs, we analyze rigidity and connectivity percolation transitions in two dimensions on lattices of l…
Infinite-cluster geometry in central-force networks
Cristian F. Moukarzel, Phillip M. Duxbury, P. L. Leath
We show that the infinite percolating cluster (with density P_inf) of central-force networks is composed of: a fractal stress-bearing backbone (Pb) and; rigid but unstressed ``dang…
Stressed backbone and elasticity of random central-force systems
Cristian F. Moukarzel, Phillip M. Duxbury
We use a new algorithm to find the stress-carrying backbone of ``generic'' site-diluted triangular lattices of up to 10^6 sites. Generic lattices can be made by randomly displacing…
