Nanosecond timescale plasticity in shock-compressed polycrystalline MgO: evidence for transition in mechanism above 100 GPa
A. Chakraborti, H. Ginestet, F. Bertrand +80
The mechanical properties of ceramics under extreme conditions directly impact applications ranging from shielding spacecrafts, designing plasma facing materials in nuclear fusion…
Volume Collapse Without a Structural Transition in Shock-Compressed FeO
C. Crépisson, T. Stevens, M. Fitzgerald +121
We report x-ray diffraction and emission spectroscopy of FeO under laser-driven shock compression between 31-199 GPa. FeO retains the B1 (rocksalt) structure along the Hugoniot to…
From diamond to BC8 to simple cubic and back: kinetic pathways to post-diamond carbon phases from metadynamics
Roman Martoňák, Sergey Galitskiy, Azat Tipeev +2
The experimental observation of elusive post-diamond carbon phases at extreme pressures remains a major challenge in high-pressure science. Using metadynamics with coordination-num…
Roadmap for warm dense matter physics
Jan Vorberger, Frank Graziani, David Riley +71
This roadmap presents the state-of-the-art, current challenges and near future developments anticipated in the thriving field of warm dense matter physics. Originating from strongl…
Extreme Metastability of Diamond and its Transformation to BC8 Post-Diamond Phase of Carbon
Kien Nguyen-Cong, Jonathan T. Willman, Joseph M. Gonzalez +9
Diamond possesses exceptional physical properties due to its remarkably strong carbon-carbon bonding, leading to significant resilience to structural transformations at very high p…
