Path Integral Monte Carlo Simulations of liquid He without Fixed Nodes: Structural Properties and Collective Excitations
Tobias Dornheim, Zhandos Moldabekov, Jan Vorberger +1
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) simulations of normal liquid He without any nodal constraints. This allows us to study the effects of…
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 …
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…
