    • Quantum-Electrodynamical Density-Functional Theory Exemplified by the Quantum Rabi Model 

      Bakkestuen, Vebjørn Hallberg; Falmår, Vegard; Lotfigolian, Maryam; Penz, Markus; Ruggenthaler, Michael; Laestadius, Andre (arXiv.org;, Journal article, 2024)
      The key features of density-functional theory (DFT) within a minimal implementation of quantum lectrodynamics are demonstrated, thus allowing to study elementary properties of quantum-electrodynamical density-functional ...

    • Quantum-electrodynamical density-functional theory for the Dicke Hamiltonian 

      Bakkestuen, Vebjørn Hallberg; Csirik, Mihaly Andras; Laestadius, Andre; Penz, Markus (arXiv.org;, Journal article, 2024)
      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 generalization of the latter to multiple modes are ...
