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…
Spin crossover in FeO under shock compression
Lélia Libon, Alessandra Ravasio, Silvia Pandolfi +17
FeO (wüstite), which exhibits complex electronic and structural properties with increasing pressure and temperature, is a key mineralogical phase for understanding deep planetary i…
Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
X-ray Microscopy and Talbot Imaging with the Matter in Extreme Conditions X-ray Imager at LCLS
Eric Galtier, Hae Ja Lee, Dimitri Khaghani +25
The last decade has shown the great potential that X-ray Free Electron Lasers (FEL) have to study High Energy Density (HED) physics. Experiments at FELs have made significant break…
Radiation and Heat Transport in Divergent Shock-Bubble Interactions
Kelin Kurzer-Ogul, Brian M. Haines, David S. Montgomery +15
Shock-bubble interactions (SBI) are important across a wide range of physical systems. In inertial confinement fusion, interactions between laser-driven shocks and micro-voids in b…
Phase transition kinetics revealed by in situ X-ray diffraction in laser-heated dynamic diamond anvil cells
Matthew Ricks, Arianna E. Gleason, Francesca Miozzi +7
We report on a novel approach to dynamic compression of materials that bridges the gap between previous static- and dynamic- compression techniques, allowing to explore a wide rang…
Multi-scale characterization of hexagonal Si-4H: a hierarchical nanostructured material
Silvia Pandolfi, Shiteng Zhao, John Turner +9
In this work we present a detailed structural characterization of Si-4H, a newly discovered bulk form of hexagonal silicon (Si) with potential optoelectronic applications. Using mu…
Atomistic deformation mechanism of silicon under laser-driven shock compression
S. Pandolfi, S. Brennan Brown, P. G. Stubley +10
Silicon (Si) is one of the most abundant elements on Earth, and it is the most important and widely used semiconductor, constituting the basis of modern electronic devices. Despite…
Planck 2015 results. XX. Constraints on inflation
Planck Collaboration, P. A. R. Ade, N. Aghanim +244
We present the implications for cosmic inflation of the Planck measurements of the cosmic microwave background (CMB) anisotropies in both temperature and polarization based on the…
Planck 2013 results. XXII. Constraints on inflation
Planck Collaboration, P. A. R. Ade, N. Aghanim +241
We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP large-angle polarization…
