Real-time solutions of coupled Ehrenfest-Maxwell-Pauli-Kohn-Sham equations: fundamentals, implementation, and nano-optical applications
René Jestädt, Michael Ruggenthaler, Micael J. T. Oliveira +2
We present the theoretical foundations and the implementation details of a density-functional approach for coupled photons, electrons, and effective nuclei in non-relativistic quan…
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…
Quantum Electrodynamical Bloch Theory with Homogeneous Magnetic Fields
Vasil Rokaj, Markus Penz, Michael A Sentef +2
We propose a solution to the problem of Bloch electrons in a homogeneous magnetic field by including the quantum fluctuations of the photon field. A generalized quantum electrodyna…
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…
Generalized Kohn-Sham iteration on Banach spaces
Andre Laestadius, Markus Penz, Erik I. Tellgren +3
A detailed account of the Kohn-Sham algorithm from quantum chemistry, formulated rigorously in the very general setting of convex analysis on Banach spaces, is given here. Starting…
