The equation of state and ionization equilibrium of dense aluminum plasma with conductivity verification
Abstract
The equation of state, ionization equilibrium, and conductivity are the most important parameters for investigation of dense plasma. The equation of state is calculated with the nonideal effects taken into consideration. The electron chemical potential and pressure, which are commonly used thermodynamic quantities, are calculated by the nonideal free energy and compared with results of a semiempirical equation of state based on ThomasFermiKirzhnits model. The lowering of ionization potential, which is a crucial factor in the calculation of nonideal Saha equation, is settled according to the nonideal free energy. The full coupled nonideal Saha equation is applied to describe the ionization equilibrium of dense plasma. The conductivity calculated by the LeeMoreDesjarlais model combined with nonideal Saha equation is compared with experimental data. It provides a possible approach to verify the accuracy of the equation of state and ionization equilibrium.

A new approach to the theoretical computation of the equation of state of dense plasmas and liquid metals is presented. The method uses the author's complete solution of Saha's equation, modified by a correction to the ionization potentials that is based on Ecker and Weizel's solutions of the Schrodinger equations for an electron in a Debye field. At densities relative to solid densities of 0.1, 1.0, and 10.0, the results over a large temperature range are in agreement with results computed using the ThomasFermi (TF) and the Debye Huckel, ThomasFermi (DHTF) models of the atom. Results for iron are comparedmore »

Equationofstate, shocktemperature, and electricalconductivity data of dense fluid nitrogen in the region of the dissociative phase transition
The dissociative phase transition of fluid nitrogen at pressures in the range 30110 GPa (0.31.1 Mbar), temperatures in the range 400014 000 K, densities up to 3.5 g/cm{sup 3}, and internal energies up to 1 MJ/mol was investigated by shock compression. Equationofstate, shocktemperature, and electricalconductivity experimental data are presented and analyzed in detail. 
Electrical conductivity and equationofstate study of warm dense copper: Measurements and quantum molecular dynamics calculations
Absolute measurements of the pressure and the electrical conductivity of expanded copper in the warm dense matter regime ({rho}=0.50.3 g/cm{sup 3} and 6000 K<T<30 000 K) are obtained in an isochoric plasma closedvessel (EPI). Quantum molecular dynamics simulations are found to be in excellent agreement with the experimental results, allowing for a detailed interpretation of the optical conductivities. A shift in energy of the 4s{yields}4p atomic line is explained by the rise of ionization with temperature. 
Equation of state of dense neon and krypton plasmas in the partial ionization regime
The compression behaviors of dense neon and krypton plasmas over a wide pressuretemperature range are investigated by selfconsistent fluid variational theory. The ionization degree and equation of state of dense neon and krypton are calculated in the densitytemperature range of 0.01–10 g/cm{sup 3} and 4–50 kK. A region of thermodynamic instability is found which is related to the plasma phase transition. The calculated shock adiabat and principal Hugoniot of liquid krypton are in good agreement with available experimental data. The predicted results of shockcompressed liquid neon are presented, which provide a guide for dynamical experiments or numerical firstprinciple calculations aimed atmore »
