Jamming Transition
Jamming phenomena arise in many systems. Granular materials, glasses and colloidal systems are just a few examples of it. This paper summerizes current effort of unifying these phenomena into a single jamming phase transition. Two examples, granular materials and colloidal suspensions, are discussed in detail to illusrate the idea. The strengths and weaknesses of this picture are addressed at t...
متن کاملJamming transition in granular systems.
Recent simulations have predicted that near jamming for collections of spherical particles, there will be a discontinuous increase in the mean contact number Z at a critical volume fraction phi(c). Above phi(c), Z and the pressure P are predicted to increase as power laws in phi-phi(c). In experiments using photoelastic disks we corroborate a rapid increase in Z at phi(c) and power-law behavior...
متن کاملThe wireless network jamming problem
In adversarial environments, disabling the communication capabilities of the enemy is a high priority. We introduce the problem of determining the optimal number and locations for a set of jamming devices in order to neutralize a wireless communication network. This problem is known as the WIRELESS NETWORK JAMMING PROBLEM. We develop several mathematical programming formulations based on coveri...
متن کاملProtocol dependence of the jamming transition.
We propose a theoretical framework for predicting the protocol dependence of the jamming transition for frictionless spherical particles that interact via repulsive contact forces. We study isostatic jammed disk packings obtained via two protocols: isotropic compression and simple shear. We show that for frictionless systems, all jammed packings can be obtained via either protocol. However, the...
متن کاملThe jamming transition of Granular Media
A statistical mechanical approach to granular material is proposed. Using lattice models from standard Statistical Mechanics and results from a mean field replica approach we find a jamming transition in granular media closely related to the glass transition in super-cooled liquids. These models reproduce the logarithmic relaxation in granular compaction and reversible-irreversible lines, in ag...
