Detecting the Amplitude Mode of Strongly Interacting Lattice Bosons by Bragg Scattering
U. Bissbort, S. Götze, Y. Li +6
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 compar…

Stochastic Mean-Field Theory for the Disordered Bose-Hubbard Model
U. Bissbort, W. Hofstetter
We investigate the effect of diagonal disorder on bosons in an optical lattice described by an Anderson-Hubbard model at zero temperature. It is known that within Gutzwiller mean-f…
