Cavity-QED systems have emerged as a powerful platform for generating highly entangled states, with significant implications for both quantum metrology and quantum simulation. A particular setting that has gained great interest given its application for matterwave interferometry is an array of free-falling atoms inside a cavity where one can encode a pseudo-spin ½ degree of freedom using a pair of selected momentum states. These are collectively coupled by exchanging cavity photons. In this talk I will discuss why this system not only is suitable for the generation of a spin exchange Hamiltonians via two photon processes, but also to engineer arbitrary collective tunable XYZ models including the so-called two-axis counter-twisting model and Hamiltonains featuring dominant multi-body interactions. All of these models are relevant for quantum enhanced interferometry and quantum simulation.
