It is well known that periodic discrete defect-containing systems support both traveling
waves and vibrational defect-localized modes. It turns out that if a periodic discrete system is …

It is well known that a modulationally unstable short-wavelength delocalized nonlinear
vibrational mode (DNVM) can create chaotic discrete breathers (DBs) in a nonlinear lattice …

Molecular dynamics (MD) is a powerful tool for modeling structural transformations in
metallic materials under irradiation, severe plastic deformation, laser processing, etc. The …

It is known that defect-free crystals can support spatially localized, large amplitude
vibrational modes with frequencies outside the linear phonon spectrum. Such excitations are …

A practical approach to the search for (quasi-) discrete breathers (DBs) in a triangular β-
FPUT lattice (after Fermi, Pasta, Ulam, and Tsingou) is proposed. DBs are obtained by …

Linear and nonlinear dynamics of hexagonal boron nitride (h-BN) lattice is studied by means
of molecular dynamics simulations with the use of the Tersoff interatomic potentials. It is …

A nonlinear chain with sixth-order polynomial on-site potential is used to analyze the
evolution of the total-to-kinetic-energy ratio during development of modulational instability of …

Discrete breather (DB) or, synonymously, intrinsic localized mode (ILM) is a spatially
localized and time-periodic vibrational mode in a defect-free nonlinear lattice, eg, in a crystal …

Uranium is an important radioactive material used in the field of nuclear energy and it is
interesting from the scientific point of view because it possesses unique structure and …

It has been shown recently that a moving discrete breathers localized in one close-packed
atomic row can be excited in a two-dimensional monoatomic crystal with Morse interaction …
