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…
Geometrical Perspective on Spin-Lattice Density-Functional Theory
Markus Penz, Robert van Leeuwen
A recently developed viewpoint on the fundamentals of density-functional theory for finite interacting spin-lattice systems that centers around the notion of degeneracy regions is…
Electron-Photon Exchange-Correlation Approximation for QEDFT
I-Te Lu, Michael Ruggenthaler, Nicolas Tancogne-Dejean +3
Quantum-electrodynamical density-functional theory (QEDFT) provides a promising avenue for exploring complex light-matter interactions in optical cavities for real materials. Simil…
