Moreau-Yosida-based Kohn-Sham Inversion for Periodic Systems
Vebjørn H. Bakkestuen, Michael F. Herbst, Vegard Falmår +2
Density-potential inversion for periodic systems within Moreau-Yosida-regularised density-functional theory is investigated, both theoretically and numerically. We develop the fram…
Quantum-Electrodynamical Density-Functional Theory Exemplified by the Quantum Rabi Model
Vebjørn H. Bakkestuen, Vegard Falmår, Maryam Lotfigolian +3
The key features of density-functional theory (DFT) within a minimalistic implementation of quantum electrodynamics are demonstrated, thus allowing to study elementary properties o…
Density-functional theory for the Dicke Hamiltonian
Vebjørn H. Bakkestuen, Mihály A. Csirik, Andre Laestadius +1
A detailed analysis of density-functional theory for quantum-electrodynamical model systems is provided. In particular, the quantum Rabi model, the Dicke model, and a generalizatio…
Kohn-Sham inversion with mathematical guarantees
Michael F. Herbst, Vebjørn H. Bakkestuen, Andre Laestadius
We use an exact Moreau-Yosida regularized formulation to obtain the exchange-correlation potential for periodic systems. We reveal a profound connection between rigorous mathematic…
