Thermal activation drives a finite-size crossover from scale-free to runaway avalanches in amorphous solids
Gieberth Rodriguez-Lopez, Ezequiel E. Ferrero
We investigate thermal avalanche dynamics in amorphous solids using elastoplastic models with local activation rules and no external driving. Dynamical heterogeneities, quantified…
Soil creep facilitated by cyclic variations of environmental conditions
Ezequiel E. Ferrero, Eduardo A. Jagla
Sloped terrains tend to creep downward over time, even when their slope is below the nominal angle of repose. This behavior can result from periodic variations in environmental con…
Consensus formation and relative stimulus perception in quality-sensitive, interdependent agent systems
David March-Pons, Ezequiel E. Ferrero, M. Carmen Miguel
We perform a comprehensive analysis of a collective decision-making model inspired by honeybee behavior. This model integrates individual exploration for option discovery and socia…
Honeybee-like collective decision making in a kilobot swarm
David March, Julia Múgica, Ezequiel E. Ferrero +1
Drawing inspiration from honeybee swarms' nest-site selection process, we assess the ability of a kilobot robot swarm to replicate this captivating example of collective decision-m…
Depinning free of the elastic approximation
Alejandro B. Kolton, Ezequiel E. Ferrero, Alberto Rosso
We model the isotropic depinning transition of a domain-wall using a two dimensional Ginzburg-Landau scalar field instead of a directed elastic string in a random media. An exact a…
The yielding of amorphous solids at finite temperatures
Ezequiel E. Ferrero, Alejandro B. Kolton, Eduardo A. Jagla
We analyze the effect of temperature on the yielding transition of amorphous solids using different coarse-grained model approaches. On one hand we use an elasto-plastic model, wit…
Properties of the density of shear transformations in driven amorphous solids
Ezequiel E. Ferrero, Eduardo A. Jagla
The strain load that triggers consecutive avalanches is a key observable in the slow deformation of amorphous solids. Its temporally averaged value display…
Creep motion of elastic interfaces driven in a disordered landscape
Ezequiel E. Ferrero, Laura Foini, Thierry Giamarchi +2
The thermally activated creep motion of an elastic interface weakly driven on a disordered landscape is one of the best examples of glassy universal dynamics. Its understanding has…
Elastic interfaces on disordered substrates: From mean-field depinning to yielding
E. E. Ferrero, E. A. Jagla
We consider a model of an elastic manifold driven on a disordered energy landscape, with generalized long range elasticity. Varying the form of the elastic kernel by progressively…
Criticality in elastoplastic models of amorphous solids with stress-dependent yielding rates
E. E. Ferrero, E. A. Jagla
We analyze the behavior of different elastoplastic models approaching the yielding transition. We propose two kind of rules for the local yielding events: yielding occurs above the…
Deformation and flow of amorphous solids: An updated review of mesoscale elastoplastic models
Alexandre Nicolas, Ezequiel E. Ferrero, Kirsten Martens +1
The deformation and flow of disordered solids, such as metallic glasses and concentrated emulsions, involves swift localized rearrangements of particles that induce a long-range de…
Spatio-temporal patterns in ultra-slow domain wall creep dynamics
Ezequiel E. Ferrero, Laura Foini, Thierry Giamarchi +2
In presence of impurities, ferromagnetic and ferroelectric domain walls slide only above a finite external field. Close to this depinning threshold, they proceed by large and abrup…
Parallel kinetic Monte Carlo simulation of Coulomb glasses
Ezequiel E. Ferrero, Alejandro B. Kolton, Matteo Palassini
We develop a parallel rejection algorithm to tackle the problem of low acceptance in Monte Carlo methods, and apply it to the simulation of the hopping conduction in Coulomb glasse…
Numerical Approaches on Driven Elastic Interfaces in Random Media
E. E. Ferrero, S. Bustingorry, A. B. Kolton +1
We discuss the universal dynamics of elastic interfaces in quenched random media. We focus in the relation between the rough geometry and collective transport properties in driven…
