Combined Pressure and Electrical-Resistivity Measurements of Warm Dense Aluminum and Titanium Plasmas

Electrical resistivity, pressure, and internal energy variation of warm dense correlated titanium (density $0.2\mathrm{g}/{\mathrm{cm}}^3$) and aluminum (density $0.1\mathrm{g}/{\mathrm{cm}}^3$) plasmas are measured using a homogeneous and thermally equilibrated media produced inside an isochoric closed-vessel plasma. These data are compared to detailed calculations based on the density functional theory. In the studied temperature range (15 000–30 000 K), it appears that both exchange-correlation and ion-ion interaction treatments are of great importance to calculate accurate theoretical values.
