Summary:
Molecular dynamics study of moving discrete breathers (DBs) in pure vanadium is carried out. The following properties of the DBs are estimated: the frequency as the function of amplitude, the degree of spatial localization and the maximum propagation velocity. Interaction of DBs with a vacancy is studied in frame of the two-dimensional model of crystal with Morse interatomic potentials.
