Cavity assisted quasiparticle damping in a Bose-Einstein condensate
S. A. Gardiner, K. M. Gheri, P. Zoller
We consider an atomic Bose-Einstein condensate held within an optical cavity and interacting with laser fields. We show how the interaction of the cavity mode with the condensate c…

Entanglement engineering of one-photon wavepackets using a single-atom source
K. M. Gheri, C. Saavedra, P. Toermae +2
We propose a cavity-QED scheme for the controlled generation of sequences of entangled single-photon wavepackets. A photon is created inside a cavity via an active medium, such as…

Quantum kinetic theory IV: Intensity and amplitude fluctuations of a Bose- Einstein condensate at finite temperature including trap loss
D. Jaksch, C. W. Gardiner, K. M. Gheri +1
We use the quantum kinetic theory to calculate the steady state and the fluctuations of a trapped Bose-Einstein condensate at finite temperature. The system is divided in a condens…
