Web14 Aug 2024 · Unfortunately, as section 6 shows, the Kohn–Sham map is not locally k-contractive for the vast majority of Kohn–Sham inputs. However, perhaps surprisingly, certain calculations do lead to a k-contractive Kohn–Sham map, such as spin-independent fcc aluminium at the PBE level of theory, figure 3. In these cases, sophisticated … http://vergil.chemistry.gatech.edu/notes/DFT-intro.pdf
Websingle-particle potential, the so-called Kohn Sham potential. In the original work of Hohenberg and Kohn (HK) [1] and Kohn and Sham (KS) [2] these theorems were proven for the ground-state density of static many-body systems. On the basis of these theorems, DFT has provided an extremely success- WebKohn–Sham density functional theory (DFT) is the most widely used electronic structure theory. Despite significant progress in the past few decades, the numerical solution of Kohn–Sham DFT problems remains challenging, especially for large-scale systems.
