Dynamical instabilities of Bose-Einstein condensates at the band-edge in one-dimensional optical lattices
Andrew J. Ferris, Matthew J. Davis, Reece W. Geursen +2
We report on experiments that demonstrate dynamical instability in a Bose-Einstein condensate at the band-edge of a one-dimensional optical lattice. The instability manifests as ra…
Precision Measurements of Collective Oscillations in the BEC-BCS Crossover
A. Altmeyer, S. Riedl, C. Kohstall +6
We report on precision measurements of the frequency of the radial compression mode in a strongly interacting, optically trapped Fermi gas of Li-6 atoms. Our results allow for a te…
Exploring the BEC-BCS Crossover with an Ultracold Gas of Li Atoms
M. Bartenstein, A. Altmeyer, S. Riedl +5
We present an overview of our recent measurements on the crossover from a Bose-Einstein condensate of molecules to a Bardeen-Cooper-Schrieffer superfluid. The experiments are perfo…
Precise determination of Li cold collision parameters by radio-frequency spectroscopy on weakly bound molecules
M. Bartenstein, A. Altmeyer, S. Riedl +9
We employ radio-frequency spectroscopy on weakly bound Li molecules to precisely determine the molecular binding energies and the energy splittings between molecular states…
Bragg spectroscopy with an accelerating Bose-Einstein condensate
R. Geursen, N. R. Thomas, A. C. Wilson
We present the results of Bragg spectroscopy performed on an accelerating Bose-Einstein condensate. The Bose condensate undergoes circular micro-motion in a magnetic TOP trap and t…
Non-adiabatic loading of a Bose-Einstein condensate into the ground state of an optical lattice
A. S. Mellish, G. Duffy, C. McKenzie +2
We present a scheme for rapid loading of a Bose-Einstein condensate into a single Bloch state of a weak optical lattice at a quasi-momentum of q = hbar k. Rabi cycling of a Bose co…
