Nanoparticles Break the Symmetry of Light
Vienna, Austria (SPX) Oct 07, 2014 - Nanoparticles can emit light into ultra-thin glass fibres. Physicists at the Vienna University of Technology have now managed to select the direction of the light using an unusual kind of coupling between spin and the direction of propagation. How can a beam of light tell the difference between left and right? At the Vienna University of Technology (TU Wien) tiny particles have been couple ... more
