R. Bolis,Guillaume Morard,Tommaso Vinci,Alessandra Ravasio,E. Bambrink,M. Guarguaglini,M. Koenig,R. Musella,F. Remus,J. Bouchet,Norimasa Ozaki,K. Miyanishi,Toshimori Sekine,Y. Sakawa,T. Sano,R. Kodama,François Guyot,Alessandra Benuzzi-Mounaix +17 more
TL;DR: In this article, the phase diagrams of periclase (MgO), enstatite, MgSiO3, and forsterite were investigated with laser driven decaying shocks and phase changes were observed between 0.2-1.2 TPa, 0.5 TPa and 0.85 TPa respectively.

TL;DR: In situ structural measurements by X-ray diffraction of selected amorphous silicates compressed statically in diamond anvil cells or dynamically by laser-generated shock compression reveal similar characteristics over a wide pressure and temperature range, reinforcing the widely used assumption that the silicate glasses studies are appropriate structural analogs for understanding the atomic arrangement of silicate liquids at these high pressures.

P. Colin-Lalu,V. Recoules,G. Salin,Thomas Plisson,E. Brambrink,Tommaso Vinci,R. Bolis,G. Huser +7 more
TL;DR: First-principles ab initio simulations of the GDP-CH principal Hugoniot showed that atomic bond dissociation has an effect on the compressibility and showed the EOS model influence on shock timing in a hydrodynamic simulation.

TL;DR: In this paper, the authors present direct measurements of equation of state and two-colour reflectivity of double-shocked α-quartz on a large ensemble of thermodynamic conditions, which were until now unexplored.
