Electrical conductivity of dense aluminium fluid

Experiments using the rapid wire evaporation technique provided data for the electrical conductivity of aluminium plasmas in a density range of (0.001-2.3) g cm-3 and for temperatures between 10000 and 285000 K. Within the frame of the linear response theory in the formulation of Zubarev, calulations of the electrical conductivity were made in the same density and temperature area. The composition of the plasma was determined within the partially ionized plasma model; the interaction between particles is considered to be a Debye potential (charged particles) and a screened polarization potential (interaction with atoms). The agreement between experimental and theoretical data is reasonable for arbitrary temperatures and densities ρ < 0.7 g cm-3. For higher densities, in the warm dense fluid region, strong correlation effects occur. These effects can be taken into account including local field corrections in the dielectric function, using a dynamic ion-ion structure factor, or by replacing the Debye potential of the electron-ion interaction with a weak pseudopotential. The latter can be determined within a density functional theory. The influence of these effects on the electrical conductivity of a warm dense aluminium fluid is shown
