Results of quasiclassical molecular-dynamics simulations of the quantum electron gas are reported. Quantum effects corresponding to the Pauli and the Heisenberg principle are modeled by an effective momentum-dependent Hamiltonian. The velocity autocorrelation functions and the dynamic structure factors have been computed. A comparison with theoretical predictions was performed. {copyright} {ital 1997} {ital The American Physical Society}

Hopping Kinetics, Quantum Dynamics and Transport

In this chapter we begin by examining simple models of electron hopping between bound states located on sites or atoms. In particular, we investigate electron hopping on classical dynamic lattices.

Quasiclassical Theory and Molecular Dynamics of Two‐Component Nonideal Plasmas

A simple model of two‐component plasmas based on pseudopotentials and quasi‐classical dynamics is derived from Planck's model. In the framework of this model bound states are treated

The method of effective potentials in the quantum-statistical theory of plasmas

We provide a survey of the concept and several successful applications of effective potentials. After introducing Kelbg's expression we discuss several useful approximations and additional

Theoretical Approaches to Quantum Monte Carlo Methods

In this chapter we substantially extend the analysis of the previous chapters to two-component partially ionized Coulomb systems with positive and negative charges and a mass ratio M varying between

Relaxation time scales in collective dynamics of liquid alkali metals.

The obtained theoretical dynamic structure factor S(k,omega) for the case of liquid lithium is found to be in excellent agreement with the recently received inelastic x-ray scattering data.

Kinetic Equations and Fluctuations in Nonideal Gases and Plasmas

This brief survey of kinetic and transport theory starts with the stochastic approach, which is mathematically simpler than kinetic equations of Boltzmann and Lenard–Balescu type. We continue with

Two‐moment modelling of the dynamic longitudinal conductivity of strongly coupled Coulomb systems

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

Stopping Power of Magnetized and Unmagnetized Plasmas: Sum Rules and Asymptotic Forms

The stopping power of magnetized and unmagnetized electronic plasmas is investigated. Within the dielectric formalism we obtain a general formula for the linear stopping power of a coupled plasma. A

Static and dynamic structure factors with account of the ion structure for high-temperature alkali and alkaline earth plasmas*

Abstract. The electron-electron, electron-ion, ion-ion and charge-charge static structure factors are calculated for alkali (at T = 30 000 K, 60 000 K, ne = 0.7 × 1021 ÷ 1.1 × 1022 cm-3) and Be2+ (at

Equations of State for Strongly Coupled Partially Ionized Plasmas

The aim of this chapter is to extend the equation of state (EOS) found in the last three chapters to higher densities.
