Density correlations in ultracold atomic Fermi gases (2007)
Belzig, Wolfgang, Schroll, Christian, Bruder, Christoph
We investigate density fluctuations in a coherent ensemble of interacting fermionic atoms. Adapting the concept of full counting statistics, well known from quantum optics and mesoscopic electron...
Decoherence and correlations in systems of trapped ultra-cold quantum gases / (2005)

Decoherence of cold atomic gases in magnetic microtraps (2003)
Schroll, Christian, Belzig, Wolfgang, Bruder, Christoph
We derive a model to describe decoherence of atomic clouds in atom-chip traps taking the excited states of the trapping potential into account. We use this model to investigate decoherence for a...
