  • The dynamic structure factor is measured in condensed matter systems via neutron scattering, but this is not applicable to ultracold atomic gases. Here, the authors show how it can be measured relying on the strongly enhanced inelastic scattering of photons off a quantum gas in an optical cavity.

  • The simplest form of the Hubbard model includes only on-site interactions, but by placing an optical lattice filled with ultracold rubidium atoms into an optical cavity the Hubbard model is implemented with competing long- and short-range interactions; four phases emerge, namely, a superfluid phase, a Mott insulating phase, a supersolid phase and a charge density wave phase.
