dc.description.abstractEnObserving and taming the effects arising from non-trivial light-matter interaction has always triggered scientists to better understand nature and develop photonic technologies. However, despite tremendous conceptual advances 1,2 , so far there have been only a few experimental proposals to reveal unusual optomechanical manifestations that are hardly seen in everyday life, such as negative radiation pressure 3,4 , transverse forces 5,6 or left-handed torques 7. Here, we report naked-eye identification of spin-dependent lateral displacements of centimetre-sized objects endowed with structured bire-fringence. Left-handed macroscopic rotational motion is also reported. The unveiled effects ultimately rely on spin-orbit optical interactions and are driven by lateral force fields that are five orders of magnitude larger than those reported previously , as a result of the proposed design. By highlighting the spin-orbit optomechanics of anisotropic and inhomogeneous media, these results allow structured light-matter interaction to move from a scientific curiosity to a new asset for the optical manipulation toolbox.
