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) …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

The accurate interpretation of experiments with matter at extreme densities and pressures is
a notoriously difficult challenge. In a recent work [Dornheim et al., Nat. Commun. 13, 7911 …

The first quasiexact ab initio path integral Monte Carlo (PIMC) investigation of the dynamic
local field correction G ̃ (q, zl; rs, Θ) in the imaginary Matsubara frequency domain is …

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) …

Dynamical properties of uniform electron fluids are studied within a nonperturbative
approach consisting in the combination of the self-consistent version of the method of …

A major challenge in the field of correlated electrons is the computation of dynamical
correlation functions. For comparisons with experiment, one is interested in their real …

By merging algorithmic Matsubara integration with discrete pole representations we present
a procedure to generate fully analytic closed form results for impurity problems at fixed …

We present a method to accelerate the numerical evaluation of spatial integrals of Feynman
diagrams when expressed on the real frequency axis. This can be realized through use of a …
