Dynamic-compression experiments on geological materials are important for understanding
the composition and physical state of the deep interior of the Earth and other planets. These …

Material equation-of-state (EOS) models, generally providing the pressure and internal
energy for a given density and temperature, are required to close the equations of …

A spectral neighbor analysis (SNAP) machine learning interatomic potential (MLIP) has
been developed for simulations of carbon at extreme pressures (up to 5 TPa) and …

Two variants of optical imaging velocimetry, specifically the one-dimensional streaked line-
imaging and the two-dimensional time-resolved area-imaging versions of the Velocity …

Realizing the potential for predictive density functional calculations of matter under extreme
conditions depends crucially upon having an exchange-correlation (XC) free-energy …

High-pressure equation of state and isentropic sound speed data for fluid silicon to
pressures of 2100 GPa (21 Mbar) are reported. Principal Hugoniot measurements were …

Accurately modeling dense plasmas over wide-ranging conditions of pressure and
temperature is a grand challenge critically important to our understanding of stellar and …

Hugoniot of full-dense nanopolycrystalline diamond (NPD) was investigated up to 1600
GPa. The Hugoniot elastic limit of NPD is 208 (±14) GPa, which is more than twice as high …

In inertial confinement fusion (ICF), polycrystalline diamond—referred to as high density
carbon (HDC)—has become a promising ablator candidate. However, with smaller grain …

We present laser-driven shock Hugoniot measurements of single-crystal (SC) 1, 3, 5-
triamino-2, 4, 6-trinitrobenzene (TATB) between 15 and 83 GPa, spanning pressures below …
