… body —QED procedure, suggested here, is not gauge invariant since the many-body effects
are evaluated to high orders and the QED … The main point is that themany-body and the QED …

We report the use of broadband heterodyne spectroscopy to perform continuous measurement
of the interaction energy E int between one atom and a high-finesse optical cavity, during …

… full QED ž QCD low-energy constants are presented. The electromagnetic charge for sea
quarks is incorporated in quenched QED ž full … quenched and unquenched QED, is estimated …

… Additionally, we show how the ground state of the full system obtains an electron–nuclear(vibronic)–photon
quasiparticle character, the vibro-polariton. The second model system we …

We study the analytic structure of the electron propagator in the entire complex p 2 plane,
using the Dyson-Schwinger equation. It is shown that in the usual ladder approximation there …

… We compare the current state-of-the-art in precision testing QED—measuring the … QED;(2)
demonstrate the ways in which successful precision predictions relate to pure QED and QED …

Full article: Cavity QED with quantum gases: new paradigms in many-body physics … We
review the recent developments and the current status in the field of quantum-gas cavity QED. …

… This paper deals with the problem of setting up a formulation of quantum electrodynamics
that is manifestly invariant under the transformations of the full conformal group. To put our …

… (32) is exact and gives the same result as QED full configuration interaction. The ground
state wave function in Eq. (32) is obtained by solving the projection equations, 54 …

… However, the absence of virtual effects and in particular of the π2-enhanced threshold corrections
in PHOTOS explains why our full QED predictions are visibly above the BaBar results. …
