This study identifies polaron-polaritons as the fundamental quasiparticles governing light-matter interactions in subwavelength atomic arrays, offering a theoretical framework to manage lattice distortions caused by optomechanical forces. By establishing design principles that mitigate motion-induced reflectivity loss, the research enables the recovery of over 99% reflectivity in two-dimensional atomic mirrors, even under realistic trap conditions. These findings provide critical insights for optimizing the stability and performance of next-generation quantum simulation and sensing platforms based on trapped atoms.
Polaron-Polaritons in Subwavelength Arrays of Trapped Atoms
arXiv:2601.21062v2 Announce Type: replace Abstract: Subwavelength arrays of atoms trapped in optical lattices or tweezers are inherently susceptible to deformations: Optomechanical forces displace atoms within their trapping potential and produce lattice distortions, which in turn modify the optical response of the array. We show that this optomechanical coupling hybridizes collective atomic excitations (polaritons) with phonons, forming polaron-polaritons -- the fundamental quasiparticles governing light-matter interactions in arrays of trapped atoms. Using analytical polaron theory and numerical simulations, we find that: (1) phonons can strongly enhance the decay of subradiant states, but also enable their efficient excitation; (2) transport of dark excitations remains remarkably robust even at low trap frequencies, except when a polariton can resonantly scatter phonons; and (3) motion reduces the reflectivity of a two-dimensional atomic mirror; by identifying design principles that mitigate this degradation, we recover reflectivity above 99% under realistic conditions. Our findings lay the foundation for analyzing motional effects in key applications and suggest new ways to harness them in state-of-the-art experiments.
