Abstract Text:
Materials under extreme compression, as the one achieved by direct laser illumination, exhibit almost-equal thermal and Coulomb energies and structural properties that are in between those of ideal gases and solids. Their understanding is critical for the calculation of the equation-of-state of the interior of giant planets as well as for inertial confinement fusion research. We will show that x-ray scattering can be used to extract static correlation properties for both the ionic and electronic subsystems. So far, dynamics properties have been limited to the electrons only, however, with the advent of 4th generation light sources there will be new possibilities to directly access ion-acoustic dynamics. Here we will summarize a few examples drawn from experiments conducted in low-Z materials using high power lasers. We will also discuss novel hybrid analytical techniques to model the full dynamical response of warm dense matter.
