Structural, thermodynamic, and transport properties of CH${}_2$ plasma in the two-temperature regime

This paper covers calculation of radial distribution functions, specific energy and static electrical conductivity of CH${}_2$ plasma in the two-temperature regime. The calculation is based on the quantum molecular dynamics, density functional theory and the Kubo-Greenwood formula. The properties are computed at 5 kK $\le$ $T_i$ $\le$ $T_e$ $\le$ 40 kK and \rho = 0.954 g/cm${}^3$ and depend severely on the presence of chemical bonds in the system. Chemical compounds exist at the lowest temperature $T_i$ = $T_e$ = 5 kK considered; they are destroyed rapidly at the growth of $T_i$ and slower at the increase of $T_e$. A significant number of bonds are present in the system at 5 kK $\le$ $T_i$ $\le$ $T_e$ $\le$ 10 kK. The destruction of bonds correlates with the growth of specific energy and static electrical conductivity under these conditions.
