Microscopic reversibility and emergent elasticity in ultrastable granular systems
Microscopic reversibility and emergent elasticity in ultrastable granular systems
In a recent paper (Zhao et al., Phys Rev X, 2022, 12: 031,021), we reported experimental observations of āultrastableā states in a shear-jammed granular system subjected to small-amplitude cyclic shear. In such states, all the particle positions and contact forces are reproduced after each shear cycle so that a strobed ā¦
