Effective Field Theory for Qed Vacuum Fluctuations
Only photons are dynamical degrees of freedom in the QED vacuum at energies well below the electron mass m. Their interactions via couplings to virtual electron-positron pairs are described to lowest order by an effective theory incorporating the Uehling and Euler-Heisenberg interactions as dominant terms. By a redefinition of the electromagnetic field, the Uehling term is shown not to contribu...

متن کاملInvestigations of a coherently driven semiconductor optical cavity QED system
Chip-based cavity quantum electrodynamics QED devices consisting of a self-assembled InAs quantum dot QD coupled to a high quality factor GaAs microdisk cavity are coherently probed through their optical channel using a fiber taper waveguide. We highlight one particularly important aspect of this all-fiber measurement setup, which is the accuracy to which the optical coupling level and optical ...
متن کاملCavity QED with quantum dots in semiconductor microcavities
Cavity quantum electrodynamic (QED) effects are studied in semiconductor microcavities embedded with InGaAs quantum dots. Evidence of weak coupling in the form of lifetime enhancement (the Purcell effect) and inhibition is found in both oxide-apertured micropillars and photonic crystals. In addition, high-efficiency, low-threshold lasing is observed in the photonic crystal cavities where only 2...
متن کاملQuantum Correlations and Intraband Coherences in Semiconductor Cavity QED
A fully quantized theory of optical interactions with semiconductors reveals quantum correlations between the field and carrier density. These quantum correlations lead to intraband coherences which live much longer than the interband dephasing time; the correlations are observed as oscillations in the time-resolved reflectivity in a pump-probe experiment on a normal-mode microcavity. Coherent ...
