Interstitial atoms influence on the quasi breather modes in the A$_3$B stoichiometry crystal with morse interaction

In this article by the method of molecular dynamics the influence of the interstitial Al atom placed into the tetrahedral and octahedral vacuums on the behavior of quasi-breather mode in the stoichiometry A$_3$B crystal, Pt$_3$Al as an example. It is obtained the dependence of the quasi-breather mode oscillation frequency on the value of the lattice distortion along the chosen direction. It is established the duration of quasi-breather mode lifetime along different crystallographic directions with the defects presence.
