Fermionic free energies from \textit{ab initio} path integral Monte Carlo simulations of fictitious identical particles
Tobias Dornheim, Zhandos Moldabekov, Sebastian Schwalbe +2
We combine the recent ensemble path integral Monte Carlo (PIMC) approach to the free energy [T.~Dornheim \textit{et al.}, \textit{Phys.~Rev.~B} \textbf{111}, L041114 (2025)] wi…

Direct free energy calculation from ab initio path integral Monte Carlo simulations of warm dense matter
Tobias Dornheim, Zhandos Moldabekov, Sebastian Schwalbe +1
We carry out highly accurate \emph{ab initio} path integral Monte Carlo (PIMC) simulations to directly estimate the free energy of various warm dense matter systems including the u…
