Abstract
This paper demonstrates programmable cavity-mediated interactions between nanoparticles in vacuum. The interaction, mediated by photons scattered by spatially separated particles in a cavity, results in strong, long-range coupling. The authors investigate the interaction strength's scaling with cavity detuning and interparticle separation, demonstrating tunability between different mechanical modes. This work enables exploring many-body effects in nanoparticle arrays, generating entanglement of motion, and using interacting particle arrays for optomechanical sensing.
