By means of molecular-dynamics simulations, it is shown that discrete breathers are excited in two-dimensional model lattice of the regulated Pt3Al alloy by periodic external action of a certain frequency. The energy of Al atoms carrying a non-linear localized mode can more than ten times exceed the mean energy of Pt atoms.
It is known that, in a molecular dynamics model of Pt3Al crystal, a discrete breather (DB) with soft type nonlinearity (DB1) can be excited, which is characterized by a high degree of localization on
