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.

In this paper, we calculate the stopping power and temperature relaxation of dense plasmas on the basis of the Coulomb logarithm using the effective potentials. These potentials take into account long‐range multi‐particle screening effects and short‐range quantum mechanical effects in two‐temperature plasmas. Ion energy losses in the plasma for different values of temperature and plasma density are calculated. The obtained results are compared with the theoretical works of other authors and with the results of molecular dynamics simulations.

... This can be explained by the specific behavior of ions, for which the calculation of CPF, PVA spectra, the concentration of vacancy clusters, and the selection of approximations produce many features that are eliminated in some way. Furthermore, with the aid of a definite diversity of flyable particles in a particular material it is possible to constitute a predefined structure and chemical compounds enough stable in a wide temperature range [4]. Then the physical and chemical properties of these materials will change. ...

... Since the development of the Ramazanov effective interaction potential, this model potential and corresponding variants have been widely employed to investigate various thermodynamic and transport properties of nonideal semiclassical dense plasmas, including the scattering of electrons from ions and atoms, [34][35][36][37][38][39] the optical reflectivity, 40 relaxation of plasma temperature and coupling parameters, 41,42 dynamical conductivity, 43,44 Coulomb logarithm and stopping power, [45][46][47] etc. In a recent work, Shalenov et al. ...
