The Kohn-Sham system in one-matrix functional theory
Ryan Requist, Oleg Pankratov
A system of electrons in a local or nonlocal external potential can be studied with 1-matrix functional theory (1MFT), which is similar to density functional theory (DFT) but takes…

Persistent current and Wigner crystallization in a one dimensional quantum ring
Marc Siegmund, Markus Hofmann, Oleg Pankratov
We use Density Functional Theory to study interacting spinless electrons on a one-dimensional quantum ring in the density range where the system undergoes Wigner crystallization. T…

Ab initio Study of Graphene on SiC
Alexander Mattausch, Oleg Pankratov
Employing density-functional calculations we study single and double graphene layers on Si- and C-terminated 1x1-6H-SiC surfaces. We show that, in contrast to earlier assumptions,…
