Dynamics of optically levitated nanoparticle arrays — •Artur Bichs¹, Uroš Delić², and Benjamin A. Stickler¹ — ¹Institute for Complex Quantum Systems, Ulm University — ²Vienna Center for Quantum Science and Technology, University of Vienna,

Optically levitated nanoparticles offer a promising platform for high-precision sensing and for exploring quantum physics with massive objects. Here, we study the dynamics of tweezer-levitated nanoparticles coupled via optical binding and via coherent scattering into a common cavity mode. We derive the corresponding quantum master equation for the joint nanoparticle array-cavity dynamics, study the linearized dynamics for two and three particles, and discuss implications for sensing and entanglement observations.
