Warm dense matter generally defines states of matter with temperatures of T ~ 0.1 – 100 eV, densities ρ ~ 0.1 – 10 times the solid density, and pressures ≥ Mbar. The macroscopic and microscopic study of this matter concerns a very broad field of physics, ranging from fundamental physics to inertial confinement fusion, as well as planetology and geophysics.
The HotCores project does include laser-driven compression experiments on Earth core alloys, coupled with X-ray diffraction characterization on X-ray free electron lasers. To this aim, Hélène Ginestet is attending the summer school on matter at extremes organized in Banyuls sur Mer, France, 4-8 september 2023. She will be learning about laser driven compression experiments, their diagnostics, modeling, and applications.
