Generalized gradient approximation correlation energy functionals based on the uniform electron gas with gap model
E. Fabiano, P. E. Trevisanutto, A. Terentjevs +1
We study the uniform electron gas with a gap model in the context of density functional theory. Based on this analysis, we construct two local gap models that realize generalized g…

Optical spectra of solids obtained by time-dependent density-functional theory with the jellium-with-gap model exchange-correlation kernel
Paolo E. Trevisanutto, Aleksandrs Terentjevs, Lucian A. Constantin +2
Within the framework of ab initio time-dependent density-functional theory (TD-DFT), we propose a static approximation to the exchange-correlation kernel based on the jellium-with-…
