A local tensor that unifies kinetic energy density and vorticity dependent exchange-correlation functionals
Sangita Sen, Erik I. Tellgren
We present a kinetic energy tensor that unifies a scalar kinetic energy density commonly used in meta-Generalized Gradient Approximation functionals and the vorticity density that…
Generalized Kohn-Sham iteration on Banach spaces
Andre Laestadius, Markus Penz, Erik I. Tellgren +3
A detailed account of the Kohn-Sham algorithm from quantum chemistry, formulated rigorously in the very general setting of convex analysis on Banach spaces, is given here. Starting…
Non-perturbative calculation of orbital- and spin effects in molecules subject to non-uniform magnetic fields
Sangita Sen, Erik I. Tellgren
External non-uniform magnetic fields acting on molecules induce non-collinear spin-densities and spin-symmetry breaking. This necessitates a general two-component Pauli spinor repr…
Universal lower bounds on the kinetic energy of electronic systems with noncollinear magnetism
Erik I. Tellgren
The distribution of noncollinear magnetism in an electronic system provides information about the kinetic energy as well as some kinetic energy densities. Two different everywhere-…
Density-Wavefunction Mapping in Degenerate Current-Density-Functional Theory
Andre Laestadius, Erik I. Tellgren
We show that the particle density, , and the paramagnetic current density, , are not sufficient to determine the set of degenerate ground…
