Optimal wave fields for micro-manipulation in complex scattering environments

A new paper with our collaborators in Nice and London just appeared in Nature Photonics and is highlighted in OSA Optics & Photonics News and in Pro-Physik. In this work we demonstrate how to design the optimal wave front to deliver the highest possible force or torque onto a target embedded in a complex environment (see illustration on the left for a wave field transferring a strong torque onto a square target).
