Harmonic damped oscillators with feedback. A Langevin study

Paolo De Gregorio, Lamberto Rondoni, Michele Bonaldi +1

We consider a system in direct contact with a thermal reservoir and which, if left unperturbed, is well described by a memory-less equilibrium Langevin equation of the second order…

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…

Dynamics of supercooled liquids: density fluctuations and Mode Coupling Theory

E. Zaccarelli, G. Foffi, P. De Gregorio +3

We write equations of motion for density variables that are equivalent to Newtons equations. We then propose a set of trial equations parameterised by two unknown functions to desc…

Slowed Relaxational Dynamics Beyond the Fluctuation-Dissipation Theorem

P. De Gregorio, F. Sciortino, P. Tartaglia +2

To describe the slow dynamics of a system out of equilibrium, but close to a dynamical arrest, we generalize the ideas of previous work to the case where time-translational invaria…
