Revisiting density-functional theory of the total current density
Andre Laestadius, Markus Penz, Erik I. Tellgren
Density-functional theory requires an extra variable besides the electron density in order to properly incorporate magnetic-field effects. In a time-dependent setting, the gauge-in…
Lower semi-continuity of universal functional in paramagnetic current-density functional theory
Simen Kvaal, Andre Laestadius, Erik I. Tellgren +1
A cornerstone of current-density functional theory (CDFT) in its paramagnetic formulation is proven. After a brief outline of the mathematical structure of CDFT, the lower semi-con…
Guaranteed convergence for a class of coupled-cluster methods based on Arponen's extended theory
Simen Kvaal, Andre Laestadius, Tilmann Bodenstein
A wide class of coupled-cluster methods is introduced, based on Arponen's extended coupled-cluster theory. This class of methods is formulated in terms of a coordinate transformati…
Convergence of the regularized Kohn-Sham iteration in Banach spaces
Markus Penz, Andre Laestadius
The Kohn-Sham iteration of generalized density-functional theory on Banach spaces with Moreau-Yosida regularized universal Lieb functional and an adaptive damping step is shown to…
