Ionization potential depression in degenerate plasmas and Pauli blocking of multi-electron ions
Gerd Röpke
The composition of partially ionised plasmas is investigated for densities and temperatures at which the free electrons are degenerate. Based on a quantum statistical approach, the…

Understanding the properties of warm dense hydrogen is of key importance for the modeling of compact astrophysical objects and to understand and further optimize inertial confineme…
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…
Virial coefficients of the Uniform Electron Gas from Path Integral Monte Carlo Simulations
Gerd Röpke, Tobias Dornheim, Jan Vorberger +2
The properties of plasmas in the low-density limit are described by virial expansions. Analytical expressions are known from Green's function approaches only for the first three vi…
Revealing Non-equilibrium and Relaxation in Warm Dense Matter
Jan Vorberger, Thomas R. Preston, Nikita Medvedev +4
Experiments creating extreme states of matter almost invariably create non-equilibrium states. These are very interesting in their own right but need to be understood even if the u…
