“…The generalization of the present approach to plasmas with higher charged ions Z ≥ 1 is also possible but not intended here. Then, comparison with new experimental data for strongly coupled metal plasmas with Γ ≫ 1 [21,22] can be performed, see [23]. The inclusion of bound state formation and the extension to higher charged ions should be considered as possible goals of future work on interpolation formula for the electrical conductivity of nonideal plasmas.…”

On the basis of a quantum-statistical approach to the electrical conductivity of nonideal plasmas we derive analytical results in the classical low-density regime, in the degenerate Born limit, and for the contribution of the Debye-Onsager relaxation effect. These explicit results are used to construct an improved interpolation formula of the electrical conductivity valid in a wide range of temperature and density which allows to compare with available experimental data of nonideal plasmas.

“…The challenge for the WDM regime is apparent from long-standing discrepancies between theoretical models and measurements of the electrical conductivity [14][15][16][17][18][19][20][21][22][23][24][25]. The theoretical studies are complex and include screened Coulomb forces that dominate interactions between ions while electrons are partially to fully degenerate.…”

“…There has been extensive work on dense plasmas, with applications ranging from inertial confinement fusion [1], Z-pinch experiments [2], X-ray Thompson scattering [3][4][5], and exploding wire experiments [6,7] to describing the astrophysics of white dwarfs [8] and the interiors of giant planets [9][10][11]. Many of these systems feature strongly non-equilibrium evolution.…”

Wave packet spreading and localization in electron-nuclear scattering

Despite its promise as a method for the simulation of time-dependent many-body quantum mechanics problems, wave packet molecular dynamics (WPMD) is limited in its use by wave packet spreading when applied to dense plasma systems. We employ more accurate methods to determine if spreading really occurs and how WPMD can be improved. A scattering process involving a single dynamic electron interacting with a periodic array of statically screened protons is used as a model problem for the comparison. We compare the numerically exact split operator Fourier transform (SOFT) method, the Wigner trajectory method (WTM), and the time dependent variational principle (TDVP). Within the framework of the TDVP, we use the standard variational form of WPMD, the single Gaussian wave packet (WP). We then generalize this form to include multiple Gaussian for the single electron as in the split WP propagation method. Wave packet spreading is predicted by all methods, so it is not the source of the unphysical behavior of WPMD at high temperatures.Instead, the Gaussian WP's inability to correctly reproduce breakup of the electron's probability density into localized density near the protons is responsible for the deviation from more accurate predictions. Extensions of WPMD must include a mechanism for breakup to occur in order to yield dynamics that lead to accurate electron densities.
