What stops flows in glassy materials?

Spatial correlations between slow-dynamics (red ellipses) and low-structural-entropy (light blue) regions in translational and rotational motion of colloidal ellipsoids with different aspect ratios. Scale bar: 20 μm. Credit: WANG Yuren Glasses have a liquid-like disordered structure but solid-like mechanical properties. This leads to one of the central mysteries of glasses: Why don’t they flow like […]
