We use an explicitly isochoric two-temperature theory to analyze recent X-ray laser scattering data for Aluminum in the ultra-fast-matter (UFM) regime up to 6 eV. The observed surprisingly low conductivities are explained by including strong electron-ion scattering effects using the phase shifts calculated via the neutral-pseudo-atom model. The applicability of the Mermin model to UFM is questioned. The static and dynamic conductivity, complex collision frequency and the plasmon line-shape are…
