Quantum generation of angular momenta of crystallites in a nanocrystalline material

It is shown that, under the effect of a point force, ordered deformation states of the Fermi type can arise in a nanocrystal. These states are characterized by an angular momentum whose magnitude (estimated in the units of Planck’s constant) depends on the number of atoms in the deformed nanocrystals and can accept macroscopic values. A qualitative explanation is given to the evolution of the strength, diffusive, and damping properties of compact nanocrystalline materials based on the assumption that the quantum generation of angular momenta of crystallites can result in states of rotational motion.
