A self-consistent model of the formation and evolution of dusty plasma structures in the ionospheres of the Earth and Mars is presented. The model allows describing the formation of a stratified dust structure as a result of dust cloud evolution in the Earth's ionosphere.

The self-consistency and basic openness of dusty plasma, charge fluctuations, high
dissipation and other features of dusty plasma system lead to the appearance of a number
of unusual and unique properties of dusty plasma. “Anomalous” heating of dusty particles,
anisotropy of temperatures and other features, parametric resonance, charge fluctuations
and interaction potential are among these unique properties. Study is ...

Dust particles under certain conditions can acquire kinetic energy of the order of
10 eV and higher, far above the temperature of gas and temperatures of ions and electrons in the
discharge. Such heating can be explained by the energy transfer between degrees of freedom of
a dusty plasma system. One of the mechanisms of such energy transfer ...

It is generally accepted that quantized vortices formed in coherent bosonic fluids are “excitations” and as such do not arise in a one-mode condensate at zero temperature. To excite them, one needs either inhomogeneities (impurities, rotation, etc.) or essentially finite fluctuations. Here, we predict a perfectly spontaneous formation of vortices even at zero temperature, which ...

The nature of two dusty plasma clouds appearing because of the impact of a meteoroid on the surface of the Moon has been discussed.

The collective behaviour of soliton ensembles (i.e. the solitonic gas) is studied using the methods of the direct numerical simulation. Traditionally this problem was addressed in the context of integrable models such as the celebrated KdV equation. We extend this analysis to non-integrable KdV–BBM type models. Some high resolution numerical results are presented in both ...

Linear and nonlinear waves in the near-surface plasma at Phobos and Deimos are considered. It is shown that the motion of the solar wind relative to photoelectrons and charged dust grains violates the isotropy of the electron distribution function in the near-surface plasma at the Martian satellites, which leads to the development of instability and excitation of high-frequency ...

It is often suggested that inter-particle distance in stable dusty plasma structures decreases with cooling as a square root of neutral gas temperature. Deviations from this dependence (up to the increase at cryogenic temperatures) found in the experimental results for the pressures range 0.1–8.0 mbar and for the currents range 0.1–1.0 mA are given. Inter-particle ...
