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…
Light-matter interaction in the long-wavelength limit: no ground-state without dipole self-energy
Vasil Rokaj, Davis M. Welakuh, Michael Ruggenthaler +1
Most theoretical studies for correlated light-matter systems are performed within the long-wavelength limit, i.e., the electromagnetic field is assumed to be spatially uniform. In…
Light-Matter Interactions via the Exact Factorization Approach
Norah M. Hoffmann, Heiko Appel, Angel Rubio +1
The exact factorization approach, originally developed for electron-nuclear dynamics, is extended to light-matter interactions within the dipole approximation. This allows for a Sc…
