Arrays of coupled mechanical oscillators have been proposed for studies of collective effects such as non-reciprocal phonon transport, investigation of topological phases or multipartite entanglement. Existing experimental architectures are usually either based on fabricated structures or use an optical cavity to mediate the interaction between multiple mechanical modes, thereby limiting the maximal number of elements and the versatility of the created interaction, as well as prohibiting individual detection of the oscillators.
Here, we present a novel platform for studying collective dynamics based on a tunable trap array of levitated nanoparticles which allows for independent control and readout of the particles motions. In addition to standard cavity-mediated setups, we exploit the light-induced dipole-dipole interactions between the particles to introduce direct coupling between them. The ability to control non-reciprocal particle interaction paves the way towards exploring many particle phenomena with massive objects. We will present this platform as well as first results on the collective dynamics of two interacting particles.
