Extremal fluctuations driving the relaxation in glassy energy landscapes
Stefan Boettcher, Paula A. Gago, Paolo Sibani
Cooperative events requiring anomalously large fluctuations are a defining characteristic for the onset of glassy relaxation across many materials. The importance of such intermitt…
Aging is a log-Poisson Process, not a Renewal Process
Stefan Boettcher, Dominic M. Robe, Paolo Sibani
Aging is a ubiquitous relaxation dynamic in disordered materials. It ensues after a rapid quench from an equilibrium "fluid" state into a non-equilibrium, history-dependent jammed…
Record Dynamics: Direct Experimental Evidence from Jammed Colloids
Dominic M. Robe, Stefan Boettcher, Paolo Sibani +1
In a broad class of complex materials a quench leads to a multi-scaled relaxation process known as aging. To explain its commonality and the astounding insensitivity to most micros…
Record Dynamics in the Parking Lot Model
Paolo Sibani, Stefan Boettcher
We present an analytical and numerical study of the parking lot model (PLM) of granular relaxation and make a connection to the aging dynamics of dense colloids. As we argue, the P…
Temporal and spatial heterogeneity in aging colloids: a mesoscopic model
Nikolaj Becker, Paolo Sibani, Stefan Boettcher +1
A coarse-grained model of dense hard sphere colloids building on simple notions of particle mobility and spatial coherence is presented and shown to reproduce results of experiment…
Aging in Dense Colloids as Diffusion in the Logarithm of Time
S. Boettcher, P. Sibani
The far-from-equilibrium dynamics of glassy systems share important phenomenological traits. A transition is generally observed from a time-homogeneous dynamical regime to an aging…
