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…
Virial relations for electrons coupled to quantum field modes
Iris Theophilou, Markus Penz, Michael Ruggenthaler +1
In this work we present a set of virial relations for many electron systems coupled to field modes, described by the Pauli--Fierz Hamiltonian in dipole approximation and using leng…
On a combinatorial problem in the Secret Santa ritual
Alexander Steinicke, Markus Penz, Bine Penz
The Secret Santa ritual, where in a group of people every member presents a gift to a randomly assigned partner, poses a combinatorial problem when considering the probabilities in…
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…
