“…It can be seen from the figures that some characteristics of the results of the present calculations of deceleration of heavy ions in an electron gas, despite several simplifications, coincide satisfactorily with the results of refs. [36]; black long-dashed line: the asymptotic form (1); solid circles: the PIC simulation data. It should be noted that for a low speed v < v th , there is a good agreement between the results of stopping power obtained in the framework of the simplified method of moments with all considered data, except for the RPA approximation.…”

The stopping power of dense electron plasmas is determined using a simplified version of the method of moments based on some interpolation formulas for the sum rules of the loss function. The energy losses of ions are evaluated with various projectile charges moving in a plasma at different values of the coupling and degeneracy parameters. The losses of slowly moving charged particles are closely examined.The results obtained are compared with those of some alternative approaches and the particle-in-cell (PIC) simulation data.

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.

We calculate the bound state energies of the hydrogen atom in semiclassical dense hydrogen plasmas modeled by the effective screened interaction potential developed by Ramazanov et al. [Phys. Rev. E 92, 023104 (2015)]. It is shown that the quantum degenerate and exchange-correlation effects of plasma electrons do not play significant roles in the region where the system exhibits bound states. The bound-continuum critical transition lines and the distribution of the ground state energies in the plasma density-temperature phase diagrams are obtained, both with and without taking into account the screening effect of the plasma ions. The dipole transition oscillator strengths and static dipole polarizabilities of the electron-ion subsystems in semiclassical dense hydrogen plasmas are calculated in a wide range of plasma parameters.
