Non-collinear orbital magnetism in molecules, nano-structures and solids

Applicants Professor Dr. Helmut Eschrig (†); Professor Dr. Gotthard Seifert
Subject Area Physical Chemistry of Solids and Surfaces, Material Characterisation

Project Description

The proposal aims at an inclusion of orbital contributions to exchange and correlation in both relativistic and non-relativistic density functional theory. Four-current density functional theory is taken as the logical basis. Orbital polarization correction terms to relativistic implementations and relativistic local density approximation plus on-site Coulomb U will be investigated and checked against many-body perturbation theory for small systems. First applications will be solids and molecules for cross-checks by applying the same functionals to both cases. Orbital polarization in transition metal monoxides, metamagnets and f-electron systems as well as the magnetic shielding tensor of small molecules and silanes will be studied.
