“…This is exactly the condition leading to large contributions from the lowest bound states to the density matrix. In order to take into account the effect of bound states explicitly we follow [12], where the bound and free states are considered as two separate contributions to the Slater sum. Both the partition function and the two-particle Slater sum can be separated as…”

Using methods previously developed by Kelbg and others for creating effective potentials for electron-ion plasmas, we investigate quarkonium potentials above deconfinement. Using results for the internal energy of a static quark-antiquark (Q Q) pair, a set of effective potentials are constructed that take into account quantum effects and symmetry conditions. Bound state effects are explicitly included in order to account for the strongly coupled nature of the plasma. It is hoped that these effective potentials will be useful in simulations of heavy quarks or plasma quasiparticles when the dynamics is treated classically.

“…Section II of this paper summarizes a number of previous works [11,12,13,14], including the definition of the Slater sum and its use in creating effective potentials. The original results of this paper start in section III, where the methods presented in section II are applied to potentials extracted from lattice data.…”

Abstract. The e − e , e − i, i − i and charge-charge static structure factors are calculated for alkali and Be 2+ plasmas using the method described by Gregori et al. in [1]. The dynamic structure factors for alkali plasmas are calculated using the method of moments [2], [3]. In both methods the screened Hellmann-Gurskii-Krasko potential, obtained on the basis of Bogolyubov's method, has been used taking into account not only the quantum-mechanical effects but also the ion structure [4].PACS. 52.27.Aj Alkali and alkaline earth plasmas, Static and dynamic structure factors -52.25.Kn Thermodynamics of plasmas -52.38.Ph X-ray scattering

“…Thus the expressions for the response functions (external longitudinal conductivity, inverse dielectric function or the dynamic structure factor, transverse conductivity, etc.) constructed within the moment approach and used in these publications, were interpolations between the correct high-frequency asymptotic behavior of the response function, like (15), and its long-time asymptotic value which is to be determined beyond the moment approach.…”

A dynamic longitudinal internal conductivity model, derived from the classical method of moments, is applied to the analysis of recent simulation data and reflectivity measurements of shock-compressed dense xenon plasmas. This model satisfies both the non-zero f −sum rule and the second non-zero sum rule, and reproduces the non-monotonicity of the conductivity of dense plasmas beyond the domain of applicability of the Drude-Lorentz model. The Drude-Lorentz model from the point of view of the theory of momentsThe classical model for the (internal) conductivity of dense plasmas and metals,is characterized by two static parameters, the static conductivity σ 0 = σ (ω = 0) = n e e 2 τm −1 = (4π) −1 ω 2 p τ and the relaxation time τ . Here n e is the number density of electrons in the system, −e and m are the electronic charge and mass, and ω p is the plasma frequency.In addition to direct measurements, the static conductivity value can be obtained as [1]Here σ ext (ω) is the external dynamic conductivity of the Coulomb system related to the internal conductivity through the well-known formula 1 [2]:Mathematically, the DL function, σ DL (z), is a simple Nevanlinna (response) function 2 with a single simple pole in the lower half-plane. In addition, the real part of σ DL (z) possesses a single finite frequency moment, which is known also as the f -sum rule:
