Light-matter hybrid-orbital-based first-principles methods: the influence of the polariton statistics
Florian Buchholz, Iris Theophilou, Klaas J. H. Giesbertz +2
A detailed understanding of strong matter-photon interactions requires first-principle methods that can solve the fundamental Pauli-Fierz Hamiltonian of non-relativistic quantum el…

Reduced Density-Matrix Approach to Strong Matter-Photon Interaction
Florian Buchholz, Iris Theophilou, Soeren Ersbak Bang Nielsen +2
We present a first-principles approach to electronic many-body systems strongly coupled to cavity modes in terms of matter-photon one-body reduced density matrices. The theory is f…
