Soliton-Complex Dynamics in Strongly Dispersive Medium Open
The concept of soliton complex in a nonlinear dispersive medium is proposed. It is shown that strongly interacting identical topological solitons in the medium can form bound soliton complexes which move without radiation. This phenomenon …

On the possibility of deuteron superfluidity associated with hydrogen dissolution in metals Open
The possibility of existence of a new type of superfluidity of the deuteron system in a metal with the number of dissolved deuterium atoms comparable with the number of atoms of the metal is discussed. If we assume that the Bose condensati…

Magnetoplasma oscillations of a two-dimensional electron layer in a bounded system Open
The spectrum of magnetoplasma oscillations of a two-dimensional electron layer in a bounded screened system is studied. It is shown that under certain conditions there exist oscillations whose frequencies are considerably lower than the el…

On singularities in the low-frequency vibration spectrum of a layered crystal Open
The high-frequency density of normal mode vibrations of a layered crystal is analyzed in the case when intersection of the constant-frequency “flexural” and “longitudinal” vibration surfaces is possible. Taking account of even small off-di…

Nonlinear localized magnetization wave in a ferromagnet as a bound state of a large number of magnons Open
A new type of exact solution is found for the one-dimensional nonlinear equations describing magnetization dynamics in anisotropic ferromagnets. The two-parameter solution has the shape of a localized wave moving with a constant velocity V…
