Efficient GW calculations for metals from an accurate ab initio polarizability
Giacomo Sesti, Alberto Guandalini, Andrea Ferretti +4
Despite its success in the study of spectroscopic properties, the method presents specific methodological challenges when applied to systems with metallic screening. Here, we…
