Correlated Light-Matter Interactions in Cavity QED — •Johannes Flick1, Heiko Appel1, and Angel Rubio1,2 — 1Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany — 2NanoBio Spectroscopy group and ETSF, Universidad del País Vasco, San Sebastián, Spain
In the electronic structure community, the quantized nature of the electrons is
usually (approximately) incorporated, whereas the electromagnetic field is mostly
treated classically. In contrast, in quantum optics, matter is typically simplified
to models with a few levels, while the quantized nature of light is fully explored.
In this work, we aim at treating both, matter and light, on an equal quantized footing.
We present exact solutions for fully quantized prototype systems
consisting of atoms or molecules placed in optical one- or two-dimensional high-Q cavities and
coupled to the quantized electromagnetic modes in the dipole or quadrupole coupling regime.
We focus on spontaneous emission, strong-coupling phenomena, dipole-dipole
couplings including van-der-Waals interactions, and Förster resonance energy transfer (FRET),
all beyond the rotating-wave approximation.
This work has implications for a future development of a time-dependent density functional theory formulation of QED [1,2]
for correlated
multi-photon configurations.
