Density correlations in ultracold atomic Fermi gases
W. Belzig, C. Schroll, C. Bruder
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 meso…
Perturbative corrections to the Gutzwiller mean-field solution of the Mott-Hubbard model
C. Schroll, Florian Marquardt, C. Bruder
We study the Mott-insulator transition of bosonic atoms in optical lattices. Using perturbation theory, we analyze the deviations from the mean-field Gutzwiller ansatz, which becom…
Decoherence of cold atomic gases in magnetic micro-traps
C. Schroll, W. Belzig, C. Bruder
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 dec…
Filtering spin with tunnel-coupled electron wave guides
M. Governale, D. Boese, U. Zuelicke +1
We show how momentum-resolved tunneling between parallel electron wave guides can be used to observe and exploit lifting of spin degeneracy due to Rashba spin-orbit coupling. A dev…
