Hot dense plasma generated in NIF, Z-pinch, and GSI is usually nonisothermal and evolves from nonideal dense quantum plasma to ideal classical plasma. The effective pair interaction approach can be used for the fast and accurate study of the various physical properties of the weakly coupled semiclassical dense plasma. Therefore, the effective interaction potentials for the description of such plasma have been developed. Thermodynamic, microscopic, and transport properties of the weakly coupled dense nonisothermal plasma have been studied [1,2,3]. First of all, it is shown that developed effective interaction potentials correctly describes thermodynamic properties [1]. Secondly, the calculations of the transport properties in the simple pair collision approximation on the basis of the effective interaction potentials give good agreement with the orbital free DFT results [2]. Thirdly, the impact of the dynamical screening and electrons degeneracy on the stopping power has been analyzed. Finally, the impact of the nonideality effect on the characteristics of the DT tablet explosion has been considered.
