Abstract [en]

We present extensive ab initio path integral Monte Carlo (PIMC) results for the spin-resolved density response of the uniform electron gas at warm dense matter conditions. This allows us to unambiguously assess the accuracy of previous theoretical approximations, thereby providing valuable insights for the future development of dielectric schemes. From a physical perspective, we observe a nontrivial manifestation of an effective electron-electron attraction that emerges in the spin-offdiagonal static density response function at strong coupling, r(s) greater than or similar to 5. All PIMC results are freely available online and can be used to benchmark approximations and simulation schemes.
