Titre | Extreme chemistry of warm dense matter |
Résumé | Laboratory experiments coupling static compression with laser-driven shocks provide access to explore the extreme chemistry of warm dense matter. I will present recent optical reflectivity and equation of state (pressure, density, temperature) measurements for nitrogen up 800 GPa (8 Mbar), 10 eV (100 000 K) and 4.1 g/cc using laser-driven shocks on precompressed fluid. The ultrafast Doppler interferometry and streaked optical pyrometry data allow to unravel major bonding changes from a molecular to a polymeric fluid and to a degenerate atomic dense plasma. I will also present new shockwave data on the melting line of Silica at several megabars. |
