Abstract

Two new theoretical methods for computing the equation of state of hot, dense matter are discussed.The ab initio phonon theory gives a first-principles calculation of lattice frequencies, which can be used to compare theory and experiment for isothermal and shock compression of solids. The ACTEX dense plasma theory has been improved to allow it to be compared directly with ultrahigh pressure shock data on low-Z materials. The comparisons with experiment are good, suggesting that these models will be useful in generating global EOS tables for hydrodynamic simulations.

Equation of state of boron nitride combining computation, modeling, and experiment

Journal Article Zhang, Shuai; Lazicki, Amy; Militzer, Burkhard; ... - Physical Review B

The equation of state (EOS) of materials at warm dense conditions poses significant challenges to both theory and experiment. We report a combined computational, modeling, and experimental investigation leveraging new theoretical and experimental capabilities to investigate warm-dense boron nitride (BN). The simulation methodologies include path integral Monte Carlo (PIMC), several density functional theory (DFT) molecular dynamics methods [plane-wave pseudopotential, Fermi operator expansion (FOE), and spectral quadrature (SQ)], activity expansion (actex), and all-electron Green's function Korringa-Kohn-Rostoker (mecca), and compute the pressure and internal energy of BN over a broad range of densities and temperatures. Our experiments were conducted at the Omegamore »« less

Improved first-principles equation-of-state table of deuterium for high-energy-density applications

Journal Article Mihaylov, D.; Karasiev, V.; Hu, S.; ... - Physical Review B

Here, we present a first-principles equation-of-state (EOS) table of deuterium aimed at improving the previously established first-principles equation-of-state table (FPEOS). The EOS table presented here, referred to as iFPEOS, introduces (1) a universal density functional theory (DFT) treatment of all density and temperature conditions, (2) a fully consistent treatment of exchange-correlation (XC) thermal effects across the entire range of temperatures covered, and (3) quantum treatment of ions. Based on ab initio molecular dynamics driven by thermal density functional theory, iFPEOS includes density points in the range 1×10^–3 $$\leqslant$$ ρ $$\leqslant$$ 1.6×10³ g/cm³ and temperature points in the range 800 Kmore »« less

Theoretical and experimental investigation of the equation of state of boron plasmas

Journal Article Zhang, Shuai; Militzer, Burkhard; Gregor, Michelle; ... - Physical Review E

We report a theoretical equation of state (EOS) table for boron across a wide range of temperatures (5.1 10⁴{5.2 10⁸ K) and densities (0.25{49 g/cm³), and experimental shock Hugoniot data at unprecedented high pressures (5608 118 GPa). The calculations are performed with first-principles methods combining path integral Monte Carlo (PIMC) at high temperatures and density functional theory molecular dynamics (DFT-MD) methods at lower temperatures. PIMC and DFT-MD cross-validate each other by providing coherent EOS (difference <1.5 Hartree/boron in energy and <5% in pressure) at 5.1 10⁵ K. The Hugoniot measurement is conducted at the National Ignition Facility using a planarmore »« less

Ti-6Al-4V to over 1.2 TPa: Shock Hugoniot experiments, ab initio calculations, and a broad-range multiphase equation of state

Journal Article Kalita, Pat; Cochrane, Kyle; Knudson, Marcus; ... - Physical Review. B

Titanium alloys are used in a large array of applications. In this work we focus our attention on the most used alloy, Ti-6Al-4V (Ti64), which has excellent mechanical and biocompatibility properties with applications in aerospace, defense, biomedical, and other fields. Here we present high-fidelity experimental shock compression data measured on Sandia’s Z machine. We extend the principal shock Hugoniot for Ti64 to more than threefold compression, up to over 1.2 TPa. We use the data to validate our ab initio molecular dynamics simulations and to develop a highly reliable, multiphase equation of state (EOS) for Ti64, spanning a broad rangemore »« less
