Amorphous-amorphous transitions in granular packings.

ABSTRACT: Polyamorphs are the amorphous counterparts of the distinct crystalline phases that are found in the phase diagram of a substance. For a given system, polyamorphs have different local structures, resulting in distinct macroscopic properties, making them important for fundamental science and applications. While previous studies have mainly focused on polyamorphism occurring in systems with an open network structure, little is known how in systems of non-spherical particles the properties of polyamorphs are affected by the orientational degrees of freedom of the particles. Here we employ computational X-ray tomography to investigate how the structure of granular packs composed of spheres, icosahedra, and dodecahedra depends on their packing density.
