Attenuating the fermion sign problem in path integral Monte Carlo simulations using the Bogoliubov inequality and thermodynamic integration
Tobias Dornheim, Michele Invernizzi, Jan Vorberger +1
Accurate thermodynamic simulations of correlated fermions using path integral Monte Carlo (PIMC) methods are of paramount importance for many applications such as the description o…
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…
Restricted configuration path integral Monte Carlo
A. Yilmaz, K. Hunger, T. Dornheim +2
Quantum Monte Carlo belongs to the most accurate simulation techniques for quantum many-particle systems. However, for fermions, these simulations are hampered by the sign problem…
Ab initio Path Integral Monte Carlo Simulations of Quantum Dipole Systems in Traps: Superfluidity, Quantum Statistics, and Structural Properties
Tobias Dornheim
We present extensive \textit{ab initio} path integral Monte Carlo (PIMC) simulations of two-dimensional quantum dipole systems in a harmonic confinement, taking into account both B…
Ab initio path integral Monte Carlo simulation of the Uniform Electron Gas in the High Energy Density Regime
Tobias Dornheim, Zhandos Moldabekov, Jan Vorberger +1
The response of the uniform electron gas (UEG) to an external perturbation is of paramount importance for many applications. Recently, highly accurate results for the static densit…
