Energy functionals serve as the basis for different models and methods in quantum and
classical many-particle physics. Arguably, one of the most successful and widely used …

Accurate knowledge of the properties of hydrogen at high compression is crucial for
astrophysics (eg, planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) …

We present extensive new ab initio path integral Monte Carlo (PIMC) results for a variety of
structural properties of warm dense hydrogen and beryllium. To deal with the fermion sign …

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 regime, from …

The accurate description of non-ideal quantum many-body systems is of prime importance
for a host of applications within physics, quantum chemistry, materials science, and related …

Accurate knowledge of the properties of hydrogen at high compression is crucial for
astrophysics (eg planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) …

The Perdew–Zunger (PZ) self-interaction correction (SIC) is an established tool to correct
unphysical behavior in density functional approximations. Yet, the PZ-SIC is well-known to …

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 …

We explore the recently introduced $\eta $-ensemble approach to compute the free energy
directly from\emph {ab initio} path integral Monte Carlo (PIMC) simulations [T …

Warm dense matter is a highly energetic phase characterized by strong correlations, thermal
effects, and quantum mechanical electrons. Thermal density functional theory is commonly …
