- Abstract: The ability to create and harness entanglement is crucial to the fields of quantum sensing andsimulation, and ultracold atom-cavity systems offer pristine platforms for this undertaking. Recently, an experiment demonstrated an effective momentum-exchange interaction between atoms in a common cavity mode. Here, we derive this interaction from a general atom-cavity model, and discuss the role of the cavity frequency shift in response to atomic motion. We show the cavity response leads to many different squeezing interactions between the atomic momentum states. Furthermore, when the atoms form a density grating, the collective motion leads to one-axis twisting, a many-body energy gap, and metrologically useful entanglement even in the presence of noise. This system offers a highly tunable, many-body quantum sensor and simulator.
