Relevance of the quadratic diamagnetic and self-polarization terms in cavity quantum electrodynamics
Christian Schäfer, Michael Ruggenthaler, Vasil Rokaj +1
Experiments at the interface of quantum-optics and chemistry have revealed that strong coupling between light and matter can substantially modify chemical and physical properties o…
Force Balance Approach for Advanced Approximations in Density Functional Theories
Mary-Leena M. Tchenkoue, Markus Penz, Iris Theophilou +2
We propose a systematic and constructive way to determine the exchange-correlation potentials of density-functional theories including vector potentials. The approach does not rely…
Guaranteed Convergence of a Regularized Kohn-Sham Iteration in Finite Dimensions
Markus Penz, Andre Laestadius, Erik I. Tellgren +1
The exact Kohn-Sham iteration of generalized density-functional theory in finite dimensions witha Moreau-Yosida regularized universal Lieb functional and an adaptive damping step i…
Kohn-Sham theory with paramagnetic currents: compatibility and functional differentiability
Andre Laestadius, Erik I. Tellgren, Markus Penz +3
Recent work has established Moreau-Yosida regularization as a mathematical tool to achieve rigorous functional differentiability in density-functional theory. In this article, we e…
