Author(s): Ulf Bissbort, Sören Götze, Yongqiang Li, Jannes Heinze, Jasper S. Krauser, Malte Weinberg, Christoph Becker, Klaus Sengstock, and Walter Hofstetter We report the first detection of the Higgs-type amplitude mode using Bragg spectroscopy in a strongly interacting condensate of ultracold atoms in an optical lattice. By the comparison of our experimental data with a spatially resolved, time-dependent bosonic Gutzwiller calculation, we obtain good q... [Phys. Rev. Lett. 106, 205303] Published Fri May 20, 2011
