Chemical potential of the warm dense electron gas from ab initio path integral Monte Carlo simulations
Tobias Dornheim, Michael Bonitz, Zhandos Moldabekov +3
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) simulation results for the chemical potential of the warm dense uniform electron gas (UEG), spanning a br…
Model-free Rayleigh weight from x-ray Thomson scattering measurements
Tobias Dornheim, Hannah M. Bellenbaum, Mandy Bethkenhagen +16
X-ray Thomson scattering (XRTS) has emerged as a powerful tool for the diagnostics of matter under extreme conditions. In principle, it gives one access to important system paramet…
Direct free energy calculation from ab initio path integral Monte Carlo simulations of warm dense matter
Tobias Dornheim, Zhandos Moldabekov, Sebastian Schwalbe +1
We carry out highly accurate \emph{ab initio} path integral Monte Carlo (PIMC) simulations to directly estimate the free energy of various warm dense matter systems including the u…
First principles simulations of dense hydrogen
Michael Bonitz, Jan Vorberger, Mandy Bethkenhagen +24
Accurate knowledge of the properties of hydrogen at high compression is crucial for astrophysics (e.g. planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) a…
Ab initio Density Response and Local Field Factor of Warm Dense Hydrogen
Tobias Dornheim, Sebastian Schwalbe, Panagiotis Tolias +3
We present quasi-exact ab initio path integral Monte Carlo (PIMC) results for the partial static density responses and local field factors of hydrogen in the warm dense matter regi…
Ab initio path integral Monte Carlo simulations of warm dense two-component systems without fixed nodes: structural properties
Tobias Dornheim, Sebastian Schwalbe, Maximilian Böhme +3
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) results for a variety of structural properties of warm dense hydrogen and beryllium. To deal with the fer…
Ultrafast Heating Induced Suppression of -band Dominance in the Electronic Excitation Spectrum of Cuprum
Zhandos Moldabekov, Thomas D. Gawne, Sebastian Schwalbe +3
The combination of isochoric heating of solids by free electron lasers (FEL) and in situ diagnostics by X-ray Thomson scattering (XRTS) allows for measurements of material properti…
Ultrahigh Resolution X-ray Thomson Scattering Measurements at the European XFEL
Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +18
Using a novel ultrahigh resolution (eV) setup to measure electronic features in x-ray Thomson scattering (XRTS) experiments at the European XFEL in Germany, we have…
Unraveling electronic correlations in warm dense quantum plasmas
Tobias Dornheim, Tilo Döppner, Panagiotis Tolias +10
The study of matter at extreme densities and temperatures has emerged as a highly active frontier at the interface of plasma physics, material science and quantum chemistry with di…
Excitation signatures of isochorically heated electrons in solids at finite wavenumber explored from first principles
Zhandos A. Moldabekov, Thomas D. Gawne, Sebastian Schwalbe +3
Ultrafast heating of solids with modern X-ray free electron lasers (XFELs) leads to a unique set of conditions that is characterized by the simultaneous presence of heated electron…
