Activation and Avalanche Length Scales in the Finite-Temperature Creep of an Elastic Interface
Giovanni Russo, Ezequiel E. Ferrero, Alejandro B. Kolton +2
We investigate the creep dynamics of a driven elastic line at finite temperature, well below the depinning threshold. We show that creep is governed by two distinct length scales.…
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…
