Breakthrough in particle control creates special half-vortex rotation
Glasgow, UK (SPX) Mar 05, 2015 - A breakthrough in the control of a type of particle known as the polariton has created a highly specialised form of rotation. Researchers at the Universities of Strathclyde and Pittsburgh, and Princeton University, conducted a test in which they were able to arrange the particles into a 'ring geometry' form in a solid-state environment. The result was a half-vortex in a 'quantised rotation ... more
