Probing extreme states of matter using high resolution inelastic X-ray scattering at hard X-ray free electron lasers

This dissertation focuses on the investigation of the stiffening of the interatomic potential of a gold lattice under intense optical irradiation. Even though this exotic behavior, predicted by theory, has been investigated experimentally using electron diffraction, its observation is still debated. Here, nanometer-thick foils of gold have been irradiated using a femtosecond optical laser pulse to energy densities higher than previously reported values and subsequently probed using X-rays. At these conditions, the response of laser-excited gold was found to be consistent with theoretical predictions. To go beyond the previous measurement, an experimental platform based on inelastic X-ray scattering at an X-ray Free Electron Laser is presented to circumvent the need for a theoretical model and thus bring an unambiguous observation of this exotic phenomena in laser-excited gold. Such observation would be important to deepen our understanding of the melting behavior of gold under extreme conditions such as the ones generated during ultrafast laser processing of materials.
