From Density Response to Energy Functionals and Back: An ab initio perspective on Matter Under Extreme Conditions

Z Moldabekov, J Vorberger, T Dornheim - arXiv preprint arXiv:2405.20356, 2024 - arxiv.org
Energy functionals serve as the basis for different models and methods in quantum and
classical many-particle physics. Arguably, one of the most successful and widely used …

Direct free energy calculation from ab initio path integral Monte Carlo simulations of warm dense matter

T Dornheim, Z Moldabekov, S Schwalbe… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …
