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…
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…
Boson Mott insulators at finite temperatures
Fabrice Gerbier
We discuss the finite temperature properties of ultracold bosons in optical lattices in the presence of an additional, smoothly varying potential, as in current experiments. Three…
Formation of spatial shell structures in the superfluid to Mott insulator transition
Simon Foelling, Artur Widera, Torben Mueller +2
We report on the direct observation of the transition from a compressible superfluid to an incompressible Mott insulator by recording the in-trap density distribution of a Bosonic…
Precision measurement of spin-dependent interaction strengths for spin-1 and spin-2 87Rb atoms
Artur Widera, Fabrice Gerbier, Simon Foelling +3
We report on precision measurements of spin-dependent interaction-strengths in the 87Rb spin-1 and spin-2 hyperfine ground states. Our method is based on the recent observation of…
Resonant control of spin dynamics in ultracold quantum gases by microwave dressing
Fabrice Gerbier, Artur Widera, Simon Foelling +2
We study experimentally interaction-driven spin oscillations in optical lattices in the presence of an off-resonant microwave field. We show that the energy shift induced by this m…
