Selection principle for the screening parameters in the mechanical response of amorphous solids

P Kaur, I Procaccia, T Samanta - Physical Review E, 2025 - APS
The mechanical response of amorphous solids to external strains is riddled with plastic
events that create topological charges in the resulting displacement field. It was recently …
