Dotted green: random phase approximation (RPA); dashed black: static approximation; solid blue: exact path integral Monte Carlo (PIMC) results20; solid red: electronic pair alignment model [Eq. (1)] introduced in this work. a Results for different values of the density parameter rs at θ = 1; b results for different values of the temperature parameter θ = kBT/EF for rs = 10.
