Ab initio path-integral Monte Carlo results for the one-particle spectral function of the warm dense electron gas

Paul Hamann, Michael Bonitz, Jan Vorberger +1

We compute quasi-exact \emph{ab initio} path-integral Monte Carlo results for the Matsubara Green's function of the uniform electron gas (UEG) at finite temperature over a broad ra…

Taylor series perspective on ab initio path integral Monte Carlo simulations with Fermi-Dirac statistics

Tobias Dornheim, Alexander Benedix Robles, Paul Hamann +6

The fermion sign problem constitutes a fundamental computational bottleneck across a plethora of research fields in physics, quantum chemistry and related disciplines. Recently, it…

Reweighting scheme for the calculation of grand-canonical expectation values in quantum Monte Carlo simulations with a fermion sign problem

Paul Hamann, Jan Vorberger, Tobias Dornheim

Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum m…

Re-weighting estimator for ab initio path integral Monte Carlo simulations of fictitious identical particles

Tobias Dornheim, Pontus Svensson, Paul Hamann +4

The fermion sign problem constitutes one of the most fundamental obstacles in quantum many-body theory. Recently, it has been suggested to circumvent the sign problem by carrying o…

Ab initio results for the plasmon dispersion and damping of the warm dense electron gas

Paul Hamann, Jan Vorberger, Tobias Dornheim +2

Warm dense matter (WDM) is an exotic state on the border between condensed matter and dense plasmas. Important occurrences of WDM include dense astrophysical objects, matter in the…

Dynamic properties of the warm dense electron gas: an ab initio path integral Monte Carlo approach

Paul Hamann, Tobias Dornheim, Jan Vorberger +2

There is growing interest in warm dense matter (WDM) -- an exotic state on the border between condensed matter and plasmas. Due to the simultaneous importance of quantum and correl…
