Time interval distributions of atoms in atomic beams
Michael Köhl, Anton Öttl, Stephan Ritter +3
We report on the experimental investigation of two-particle correlations between neutral atoms in a Hanbury Brown and Twiss experiment. Both an atom laser beam and a pseudo-thermal…
Observing the Formation of Long-range Order during Bose-Einstein Condensation
Stephan Ritter, Anton Öttl, Tobias Donner +3
We have experimentally investigated the formation of off-diagonal long-range order in a gas of ultracold atoms. A magnetically trapped atomic cloud prepared in a highly nonequilibr…
Bose-Fermi Mixtures in a Three-dimensional Optical Lattice
Kenneth Günter, Thilo Stöferle, Henning Moritz +2
We have studied mixtures of fermionic K and bosonic Rb quantum gases in a three-dimensional optical lattice. We observe that an increasing admixture of the fermionic…
Strongly Interacting Atoms and Molecules in a 3D Optical Lattice
Michael Köhl, Kenneth Günter, Thilo Stöferle +2
We report on the realization of a strongly interacting quantum degenerate gas of fermionic atoms in a three-dimensional optical lattice. We prepare a band-insulating state for a tw…
Hybrid apparatus for Bose-Einstein condensation and cavity quantum electrodynamics: Single atom detection in quantum degenerate gases
Anton Öttl, Stephan Ritter, Michael Köhl +1
We present and characterize an experimental system in which we achieve the integration of an ultrahigh finesse optical cavity with a Bose-Einstein condensate (BEC). The conceptuall…
Fermionic atoms with tunable interactions in a 3D optical lattice
Thilo Stöferle, Henning Moritz, Christian Schori +3
We report on the realization of a quantum degenerate atomic Fermi gas in an optical lattice. Fermi surfaces of noninteracting fermions are studied in a three-dimensional lattice. U…
