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…

Dressed-Orbital Approach to Cavity Quantum Electrodynamics and Beyond
S. E. B. Nielsen, C. Schäfer, M. Ruggenthaler +1
We present a novel representation of coupled matter-photon systems that allows the application of many-body methods developed for purely fermionic systems. We do so by rewriting th…
