Optical matter machine (IMAGE)
Caption
Researchers created an optical matter machine that operates much like a mechanical machine in which if one gear is turned, a smaller interlocking gear will spin in the opposite direction (a). The optical matter machine (b) uses circularly polarized light to create a nanoparticle array that acts like the larger gear by spinning in the optical field. This makes a probe particle - analogous to the second smaller gear - orbit the nanoparticle array in the opposite direction.
