Data for generating the figures of "Strong coupling and dark modes in the motion of a pairof levitated nanoparticles" https://doi.org/10.1103/t33b-f1b2

We experimentally investigate a system composed of two levitating nanospheres whose motionsare indirectly coupled via coherent scattering in a single optical cavity mode. The nanospheresare loaded into a double longitudinal tweezer created with two lasers at different wavelengths,where chromatic aberration leads to the formation of two separate trapping sites. We achievestrong coupling between each pair of modes in the transverse plane of the tweezer, and we showthe emergence of dark modes in the overall coupled motion. The observed features are ubiquitousin a variety of classical and quantum systems. As such, our experiment will allow us to explorethe classical analog of typically quantum dynamics, and in further developments to investigate thetransition to the quantum domain.
