Glass transition in granular media
– In the framework of schematic hard spheres lattice models for granular media we investigate the phenomenon of the " jamming transition ". In particular, using Edwards' approach, by analytical calculations at a mean field level, we derive the system phase diagram and show that " jamming " corresponds to a phase transition from a " fluid " to a " glassy " phase, observed when crystallization is...
متن کاملGlass transition for driven granular fluids.
We investigate the dynamics of a driven system of dissipative hard spheres within mode-coupling theory. The dissipation is modeled by normal restitution, and driving is applied to individual particles in the bulk. In such a system, a glass transition is predicted for a finite transition density. With increasing dissipation, the transition shifts to higher densities. Despite the strong driving a...
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...
متن کاملTowards the Glass Transition in Vibrated Granular Matter
Granular materials are large sets of macroscopic particles that interact solely via contact forces. The static behavior depends on the contact network and on the surface friction forces between grains; when they are set in motion (typically by vibrations) their dynamics is dominated by inelastic collisions. For these reasons granular media show an extremely rich phenomenology, ranging from flui...
متن کاملSigns of a Gardner Transition in a Granular Glass
T he glass transition, in which materials become so viscous that they cannot flow even on extremely long time scales, has baffled scientists for over one hundred years. Experiments have shown that the viscosity can increase in atomic and polymeric liquids by more than 15 orders of magnitude—think of going from the viscosity of water to that of asphalt—over a narrow range of decreasing temperatu...
