Expansion of a quantum gas released from an optical lattice
F. Gerbier, S. Trotzky, S. Foelling +9
We analyze the interference pattern produced by ultracold atoms released from an optical lattice. Such interference patterns are commonly interpreted as the momentum distributions…
Time-resolved Observation and Control of Superexchange Interactions with Ultracold Atoms in Optical Lattices
S. Trotzky, P. Cheinet, S. Fölling +7
Quantum mechanical superexchange interactions form the basis of quantum magnetism in strongly correlated electronic media. We report on the direct measurement of superexchange inte…
Quantum Spin Dynamics of Mode-Squeezed Luttinger Liquids in Two-Component Atomic Gases
Artur Widera, Stefan Trotzky, Patrick Cheinet +6
We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic…
State preparation and dynamics of ultracold atoms in higher lattice orbitals
Torben Mueller, Simon Foelling, Artur Widera +1
We report on the realization of a multi-orbital system with ultracold atoms in the excited bands of a 3D optical lattice by selectively controlling the band population along a give…
Coherent collisional spin dynamics in optical lattices
Artur Widera, Fabrice Gerbier, Simon Foelling +3
We report on the observation of coherent, purely collisionally driven spin dynamics of neutral atoms in an optical lattice. For high lattice depths, atom pairs confined to the same…
Spatial quantum noise interferometry in expanding ultracold atom clouds
Simon Foelling, Fabrice Gerbier, Artur Widera +3
In a pioneering experiment, Hanbury Brown and Twiss (HBT) demonstrated that noise correlations could be used to probe the properties of a (bosonic) particle source through quantum…
