  • The medium range order in amorphous materials has a profound impact on their properties. Yuan et al. investigate how non-spherical particle shape affects granular packing and reveal amorphous-amorphous transitions associated with an orientational order of particles at intermediate length scales.

  • Granular materials exhibit yielding behaviors rather different from glasses that can be elastic. Here, Yuan et al. show a cross-over from creep to diffusive dynamics in three-dimensional granular systems under cyclic shear and that the relaxation process depends on the roughness of the constituent particles.

  • When applying sufficient strain, the flow of dense granular matter becomes critical. It is now shown that this state corresponds to random loose packing for spheres with different friction coefficients and that these packings can be mapped onto the frictionless hard-sphere system.

  • Granular matter exhibit slow dynamics similar to glassy systems, but the impact of particle friction on relaxation processes remains unclear. Through experiments on tapped granular packings, the authors find that the relaxation behaviors of granular systems with varying frictional properties consistently follow a generalized law of atomic glasses, suggesting a quasi-universal mechanism shared by both systems.

  • The study of the general factors underlying clogging are fragmented and application-driven due to its broad spectrum of applications. The authors propose a holistic understanding of the clogging process by investigating the clogging of a granular hopper flow using high-speed imaging, finding a signature formation of precursory chain structures.
