A molecular Bose-Einstein condensate emerges from a Fermi sea
Markus Greiner, Cindy A. Regal, Deborah S. Jin
The realization of fermionic superfluidity in a dilute gas of atoms, analogous to superconductivity in metals, is a long-standing goal of ultracold gas research. Beyond being a new…
Entanglement interferometry for precision measurement of atomic scattering properties
Artur Widera, Olaf Mandel, Markus Greiner +3
We report on a two-particle matter wave interferometer realized with pairs of trapped 87Rb atoms. Each pair of atoms is confined at a single site of an optical lattice potential. T…
Lifetime of molecule-atom mixtures near a Feshbach resonance in 40K
C. A. Regal, M. Greiner, D. S. Jin
We report a dramatic magnetic field dependence in the lifetime of trapped, ultracold diatomic molecules created through an s-wave Feshbach resonance in 40K. The molecule lifetime i…
Detection of spatial correlations in an ultracold gas of fermions
M. Greiner, C. A. Regal, C. Ticknor +2
Spatial correlations are observed in an ultracold gas of fermionic atoms close to a Feshbach resonance. The correlations are detected by inducing spin-changing rf transitions betwe…
Controlled Collisions for Multiparticle Entanglement of Optically Trapped Atoms
Olaf Mandel, Markus Greiner, Artur Widera +3
Entanglement lies at the heart of quantum mechanics and in recent years has been identified as an essential resource for quantum information processing and computation. Creating hi…
Coherent transport of neutral atoms in spin-dependent optical lattice potentials
Olaf Mandel, Markus Greiner, Artur Widera +3
We demonstrate the controlled coherent transport and splitting of atomic wave packets in spin-dependent optical lattice potentials. Such experiments open intriguing possibilities f…
