Low-scaling \textit{GW} calculations of quasi-particle energies for extended systems within the numerical atomic orbital framework
A NAO-based LRI-enhanced space-time GW method reduces scaling to O(N^2) while matching conventional results for quasi-particle energies in solids with fewer than 100 atoms.
