Abstract
Levitated optomechanics is moving toward larger and more complicated systems with many interacting particles and modes. As these systems grow, it becomes harder to control them and to extract useful information from measurements. In this talk, I approach these challenges from the perspective of wave scattering. First, I show that far-field scattering measurements can be used to design optical fields that cool levitated particles, even without a detailed microscopic model of the system. This opens a route to black-box control through wavefront shaping. Second, I show that Fisher information in scattering systems follows a local continuity law, which helps explain how information propagates to the detector and where it is lost. Together, these results motivate a unified scattering matrix based framework for optical control, measurement, and decoherence, with links to optimization, control theory, and machine-learning based design in complex optomechanical systems.
