Motivated by the current high interest in the field of warm dense matter research, in this
article we review the uniform electron gas (UEG) at finite temperature and over a broad …

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 …

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 …

Warm dense matter (WDM)—an exotic state of highly compressed matter—has attracted
increased interest in recent years in astrophysics and for dense laboratory systems. At the …

This chapter gives an introduction to interacting many-body systems. Interaction effects give
rise to collective behavior, dominated by mean field effects, as well as to correlations. We …

In a recent Letter [T. Dornheim et al., Phys. Rev. Lett. 117, 156403 (2016) PRLTAO 0031-
9007 10.1103/PhysRevLett. 117.156403], we presented the first quantum Monte Carlo …

An accurate analytical parametrization for the exchange-correlation free energy of the
homogeneous electron gas, including interpolation for partial spin polarization, is derived …

Rigorous diagnostics of experiments with warm dense matter are notoriously difficult. A key
method is X-ray Thomson scattering (XRTS), but the interpretation of XRTS measurements is …

We perform ab initio quantum Monte Carlo (QMC) simulations of the warm dense uniform
electron gas in the thermodynamic limit. By combining QMC data with the linear response …

Hydrogen at extreme temperatures and pressures is of key relevance for cutting-edge
technological applications, with inertial confinement fusion research being a prime example …
