New Form of Matter Melds Lasers, Superconductors

sterlingda writes "Physicists at the University of Pittsburgh have demonstrated a new form of matter that melds the characteristics of lasers and superconductors. The work introduces a new method of moving energy from one point to another as well as a low-energy means of producing a light beam like that from a laser. The new state is a solid filled with a collection of energy particles known as 'polaritons' that have been trapped and slowed using a technique similar to that used to produce a Bose-Einstein condensate. The work is published in the May 18 issue of Science (subscription required to read beyond the abstract)."
