Correlated photon-electron wavefunctions in cavity Quantum Electrodynamics — •Heiko Appel1, Johannes Flick1, Rene Jestaedt1, and Angel Rubio1,21Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany — 2NanoBio Spectroscopy group and ETSF, Universidad del País Vasco, San Sebastián, Spain

Experimental progress in recent years has enabled the fabrication of Fabry-Perot resonators with high optical quality factors (high-Q). Such cavities allow to study the interaction of matter with a quantized light field at the single-photon level (Nobel prize 2012). In this talk we present the real-time evolution of correlated photon-electron wavefunctions in optical one- and two-dimensional high-Q cavities. We discuss implications for a multi-component density functional theory for Quantum Electrodynamics [1,2] based on the time-dependent electron density and the photon energy density.
