Abstrakt

Recent experiments demonstrate highly tunable nonreciprocal coupling between levitated nanoparticles due to optical binding [J. Rieser, Science 377, 987 (2022)0036-807510.1126/science.abp9941]. In view of recent experiments cooling nanoparticles to the quantum regime, we here develop the quantum theory of small dielectric objects interacting via the forces and torques induced by scattered tweezer photons. The interaction is fundamentally non-Hermitian and accompanied by correlated quantum noise. We present the corresponding Markovian quantum master equation and show how to reach nonreciprocal and unidirectional coupling. Our work provides the theoretical tools for exploring and exploiting the rich quantum physics of nonreciprocally coupled nanoparticle arrays.
