Exact Solution of a Jamming Transition: Closed Equations for a Bootstrap Percolation Problem
Paolo De Gregorio, Aonghus Lawlor, Phil Bradley +1
Jamming, or dynamical arrest, is a transition at which many particles stop moving in a collective manner. In nature it is brought about by, for example, increasing the packing dens…
Geometry of Empty Space is the Key to Near-Arrest Dynamics
Aonghus Lawlor, Paolo De Gregorio, Phil Bradley +2
We study several examples of kinetically constrained lattice models using dynamically accessible volume as an order parameter. Thereby we identify two distinct regimes exhibiting d…
Clarification of the Bootstrap Percolation Paradox
Paolo De Gregorio, Aonghus Lawlor, Phil Bradley +1
We study the onset of the bootstrap percolation transition as a model of generalized dynamical arrest. We develop a new importance-sampling procedure in simulation, based on rare e…
