Analytic static structure factors and pair-correlation functions for the unpolarized homogeneous electron gas
Analytic static structure factors and pair-correlation functions for the unpolarized homogeneous electron gas
We propose a simple and accurate model for the electron static structure factors (and corresponding pair-correlation functions) of the three-dimensional unpolarized homogeneous electron gas. Our spin-resolved pair-correlation function is built up with a combination of analytic constraints and fitting procedures to quantum Monte Carlo data, and, in comparison to previous …
