Momentum distribution of the Uniform Electron Gas at finite temperature: Effects of spin-polarization
Tobias Dornheim, Jan Vorberger, Burkhard Militzer +1
We carry out extensive direct path integral Monte Carlo (PIMC) simulations of the uniform electron gas (UEG) at finite temperature for different values of the spin-polarization …

Fermion Sign Problem in Path Integral Monte Carlo Simulations: Grand-canonical ensemble
Tobias Dornheim
We present a practical analysis of the fermion sign problem in fermionic path integral Monte Carlo (PIMC) simulations in the grand-canonical ensemble (GCE). As a representative mod…

Ab initio path integral Monte Carlo approach to the momentum distribution of the uniform electron gas at finite temperature without fixed nodes
Tobias Dornheim, Maximilian Böhme, Burkhard Militzer +1
We present extensive new \textit{ab intio} path integral Monte Carlo results for the momentum distribution function of the uniform electron gas (UEG) in the warm de…
