Equation of State and Hugoniot Curve in Warm Dense Hydrogen
We investigate warm dense matter by performing quantum molecular dynamics (QMD) simulations based on density functional theory (DFT). Dense hydrogen is the main component in giant planets and, therefore, of particular interest. We present new results for the equation of state and the Hugoniot curve and compare with experiments. Density functional theory is based on the theorems of Hohenberg and...
متن کاملA Generalized Equation of State for Hot, Dense Matter
An equation of state for hot, dense matter is presented in a form that is suuciently rapid to use directly in hydrodynamical simulations, for example, in stellar collapse calculations. It contains an adjustable nuclear force that accurately models both potential and mean-eld interactions, and it allows for the input of various nuclear parameters, some of which are not yet experimentally well-de...
متن کاملFirst-Principles Equation of State Calculations of Warm Dense Nitrogen
Using path integral Monte Carlo (PIMC) and density functional molecular dynamics (DFT-MD) simulation methods, we compute a coherent equation of state (EOS) of nitrogen that spans the liquid, warm dense matter (WDM), and plasma regimes. Simulations cover a wide range of densitytemperature space, 1.5 − 13.9 g cm and 10 − 10 K. In the molecular dissociation regime, we extend the pressure-temperatu...
متن کاملEquation-of-state Model for Shock Compression of Hot Dense Matter
A quantum equation-of-state model is presented and applied to the calculation of high-pressure shock Hugoniot curves beyond the asymp-totic fourfold density, close to the maximum compression where quantum effects play a role. An analytical estimate for the maximum attainable compression is proposed. It gives a good agreement with the equation-of-state model.
متن کاملViscosity and mutual diffusion of deuterium-tritium mixtures in the warm-dense-matter regime.
We have calculated viscosity and mutual diffusion of deuterium-tritium (DT) in the warm, dense matter regime for densities from 5 to 20 g/cm{3} and temperatures from 2 to 10 eV, using both finite-temperature Kohn-Sham density-functional theory molecular dynamics (QMD) and orbital-free molecular dynamics (OFMD). The OFMD simulations are in generally good agreement with the benchmark QMD results,...
