DY 19: Franco-German Session on Granular Matter I
Dienstag, 10. März 2026, 09:30–12:45, HÜL/S186
Granular media exhibit rich collective behavior arising from simple interactions such as friction, collisions, elasticity, and confinement. This session brings together experimental, numerical, and theoretical studies addressing key transitions in granular systems, including jamming, viscous-to-inertial regimes, clustering, gas cooling, and impact dynamics, highlighting the links between microscopic mechanisms and macroscopic responses.
Organized by Baptiste Darbois Texier (Paris) and Franco Antonio Tapia Uribe (Dresden)
