During irradiation, bombardment with energetic particles, or plasma treatment, structural
transformations occur in materials, in which point defects play a very important role. Highly …

Among a wide variety of point defects, crowdions can be distinguished by their high energy
of formation and relatively low migration barriers, which makes them an important agent of …

Rotobreathers in the chain of coupled linearly elastic rotators are analyzed. Each rotator is a
particle connected by a massless elastic rod with a frictionless pivot; it has two degrees of …

The rapid development of new technologies is often associated with the realization of
nonequilibrium states in materials, in which new mechanisms of structure evolution, different …

It has recently been shown that supersonic 2-crowdions are much more efficient at
transferring mass along the crystal lattice compared to classical supersonic crowdions. This …

In this work, the mass transfer along an octahedral channel in an fcc copper single crystal is
studied for the first time using the method of molecular dynamics. It is found that the initial …

Simulation of crystal lattices under conditions far from equilibrium is an increasingly
important subject of research and requires confidence in the validity of the applied …

Supratransmission waves are stable objects that can exist in different discrete environments.
In this paper, we consider the interaction of such waves with single edge dislocations of …

Recently, much attention has been paid to the study of supersonic 2-crowdions, since they
are more efficient in mass transfer in comparison with classical supersonic crowdions. A …

Crowdion being an interstitial type zero dimensional defect can form different complexes
and clusters allowing the realization of effective propagation modes inaccessible for a single …
