We perform calculations of the 3D finite-temperature homogeneous electron gas in the warm-dense regime $$(r_s ≡ (3/4πn)^{1/3}a^{-1}_0 = 1.0 – 40.0$$ and $$Θ ≡ T/T_F = 0.0625 – 8.0)$$ using restricted path-integral Monte Carlo simulations. Precise energies, pair correlation functions, and structure factors are obtained. For all densities, we find a significant discrepancy between the ground state parametrized local density approximation and our results around $$T_F$$. These results can be used as a benchmark for developing finite-temperature density functionals, as well as input for orbital-free density function theory formulations.
