Abstract: We compute the energy needed to add or remove one particle from a homogeneous system of N bosons on a torus. We focus on the mean-field limit when N becomes large and the strength of… read more here.

Abstract: 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… read more here.
