Optimized Effective Potential Method in Current-Spin Density Functional Theory
S. Pittalis, S. Kurth, N. Helbig +1
Current-spin density functional theory (CSDFT) provides a framework to describe interacting many-electron systems in a magnetic field which couples to both spin- and orbital-degree…

Exchange-correlation orbital functionals in current-density-functional theory: Application to a quantum dot in magnetic fields
N. Helbig, S. Kurth, S. Pittalis +2
The description of interacting many-electron systems in external magnetic fields is considered in the framework of the optimized effective potential method extended to current-spin…

Performance of one-body reduced density matrix functionals for the homogeneous electron gas
N. N. Lathiotakis, N. Helbig, E. K. U. Gross
The subject of this study is the exchange-correlation-energy functional of reduced density matrix functional theory. Approximations of this functional are tested by applying them t…
