Author(s): Raphael Lopes, Christoph Eigen, Adam Barker, Konrad G. H. Viebahn, Martin Robert-de-Saint-Vincent, Nir Navon, Zoran Hadzibabic, and Robert P. Smith Using two-photon Bragg spectroscopy, we study the energy of particlelike excitations in a strongly interacting homogeneous Bose-Einstein condensate, and observe dramatic deviations from Bogoliubov theory. In particular, at large scattering length a the shift of the excitation resonance from the free… [Phys. Rev. Lett. 118, 210401] Published Tue May 23, 2017
