On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas
ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime
ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Predicting the Uniform Electron Gas Stopping Power at Moderate and Strong Coupling
ABSTRACT This paper presents a detailed study of the stopping power of a homogeneous electron gas in moderate and strong coupling regimes using the self‐consistent version of the method of moments as the key theoretical approach capable of expressing the dynamic characteristics of the system in terms of the static ones, which are the moments.
