| Research Abstract |
Electrical conductivity in warm dense state have been evaluated by pulsed-power discharge with isochoric heating, in which has been realized by metallic foam filled in a sapphire capillary. The electrical conductivity and the internal energy of warm dense gold in several densities have been estimated by the voltage and current waveforms, directly. The results indicated that the electrical conductivity in a region of several MJ/kg of internal energy is estimated to be 104~105 S/m. It indicated that the density dependence of the electrical conductivity in warm dense gold evaluated by the pulsed-power discharge with isochoric heating was different behavior compared to the exploding wire in water. We have also demonstrated the spectroscopic ellipsometry for evaluating AC electrical conductivity for warm dense copper.
