Abstract

In ultracold atoms settings, inelastic light scattering is a preeminent technique to reveal static and dynamic properties at nonzero momentum. In this work, we investigate an array of one-dimensional trapped Bose gases, by measuring both the energy and the momentum imparted to the system via light scattering experiments. The measurements are performed in the weak perturbation regime, where these two quantities - the energy and momentum transferred - are expected to be related to the dynamical structure factor of the system. We discuss this relation, with special attention to the role of in-trap dynamics on the transferred momentum.
