“…In previous works, within binary scattering approximation, various transport properties of dense plasmas with weakly degenerate electrons have been investigated using effective (screened) potential approach. [ 13–20 ] These investigations were limited to the equilibrium state. However, recently it was shown that the presence of the flux of electrons relative to ions leads to the creation of the wake field, which creates effective ion‐ion attraction regions.…”

Transport properties of the ionic component of dense plasmas are investigated on the basis of effective potentials taking into account the presence of an external alternating electrical (laser) field. The latter generates single particle oscillations of electrons and significantly changes the screening of the test charge in plasma. Therefore, transport coefficients become non-monotonic function of the oscillation frequency. The results for the diffusion and viscosity coefficients are presented. These transport coefficients are computed using the generalized Coulomb logarithm within the Chapman-Enskog model for the fluid description. It was revealed that the oscillation of the electrons in the alternating external field with the frequency ≳ 2 (with being plasma frequency) results in the significant reduction of the ionic diffusion and viscosity coefficients. In contrast, at ≲ , the ionic diffusion and viscosity coefficients are larger compared to the case without the external field impact.

This article is devoted to the study of the glow intensity of radio-frequency capacitive discharge plasma with nanoparticles for further use in lighting devices. The process of carbon nanoparticles synthesis in the radiofrequency discharge was investigated, and the influence of plasma parameters on the formation and growth of the material was also studied. A method for determining the diameter of nanoparticles based on self-bias voltage and electron density is considered. It is revealed that the diameter of nanoparticles has a considerable influence on the optical properties of the plasma, in particular, on the emission intensity. Based on the obtained data, laboratory samples of lighting devices with improved luminous intensities were developed.

“…Temperature relaxation between electrons and ions in dense plasma is a key problem in understanding the interactions in high energy density physics . Particularly for inertial confinement fusion (ICF), the values of energy transfer rates are necessary to simulate energy depositions . The experiments for diagnosing the process of temperature relaxation are currently advancing rapidly due to powerful lasers such as the OMEGA, X‐ray free electron lasers, and the National Ignition Facility .…”

In this paper, the relaxation properties of a fully ionized, hot, ideal plasma have been studied using the molecular dynamics method. As an example, the classical problem of equalization of the electron and ion temperatures for various mass ratios is considered, the relaxation times for temperatures is determined, and the influence of the number of particles and the type of boundary conditions on the simulation results is studied. The simulation results are compared with the available theoretical results.
