Modeling partially-ionized dense plasma using wavepacket molecular dynamics
Daniel Plummer, Pontus Svensson, Wiktor Jasniak +3
We develop a wave packet molecular dynamics framework for modeling the structural properties of partially-ionized dense plasmas, based on a chemical model that explicitly includes…
Statistical theory of electronic degrees of freedom in wave packet molecular dynamics
Daniel Plummer, Pontus Svensson, Wiktor Jasniak +3
We derive statistical distributions for the degrees of freedom in wave packet molecular dynamics models. Specifically, a theory is developed for the width distributions of Gaussian…
Ionisation Calculations using Classical Molecular Dynamics
Daniel Plummer, Pontus Svensson, Dirk O. Gericke +3
By performing an ensemble of molecular dynamics simulations, the model-dependent ionisation state is computed for strongly interacting systems self-consistently. This is accomplish…
Modelling of warm dense hydrogen via explicit real time electron dynamics: Dynamic structure factors
Pontus Svensson, Yusuf Aziz, Tobias Dornheim +5
We present two methods for computing the dynamic structure factor for warm dense hydrogen without invoking either the Born-Oppenheimer approximation or the Chihara decomposition, b…
Modelling of warm dense hydrogen via explicit real time electron dynamics: Electron transport properties
Pontus Svensson, Patrick Hollebon, Daniel Plummer +2
We extract electron transport properties from atomistic simulations of a two-component plasma, by mapping the long-wavelength behaviour to a two-fluid model. The mapping procedure…
