Prospects for the use of dynamic discrete breathers in nanofibers crystals stoichiometry A3B with the structure of L12

Abstract

By method of molecular dynamics shows the possibility of moving discrete breathers with a hard type of nonlinearity along the crystal nanofibers Pt3Al. Consider the collision of discrete breathers with a hard type of nonlinearity, revealed that the interaction considered breathers cause partial dissipation of energy in the breather sublattice Al. The results may be useful in explaining the effects of low-dose and long-range effect. The possibility of the transfer of energy through the crystal over long distances can lead to structural transformation far away from the focus of excitation of these localized objects. They can will influence the transformation of the energy of the crystal structure, activate motion objects such as dislocations, Frenkel pairs or crowdion complexes.
