Foams, colloidal glasses, granular materials or bulk metallic glasses respond elastically when a small external strain is applied, but they yield and flow due to internal plastic rearrangements if the drive is large enough. The dynamical crossover between these two regimes can be understood as a dynamical phase transition known as the yielding transition, whose study has gained an increasing interest in the last few years.
On the other hand, systems such as magnetic and ferroelectric domain walls, contact lines in wetting and fracture fronts, can be described as elastic objects embedded in a disordered medium that slide only above a finite driven force, the depinning force. This dynamical phase transition has been studied for more than 30 years now.
The goal of this mini-workshop, in short, is to dig into the similarities and differences between these two phenomena.
The workshop is organized as a part of the visit of Dr. Alejandro Kolton to LIPhy, founded by the CPTGA (Centre de Physique Théorique de Grenoble-Alpes)
