Temperature dependence of the dynamic structure factor of the electron liquid via analytic continuation
Thomas Chuna, Maximilian P. Böhme, Tobias Dornheim
We present new analytic continuation results for the dynamic structure factor of the uniform electron liquid based on quasi-exact \emph{ab initio} path integral M…
