+ - Scientists create never-before-seen, lightsaber-like form of matter->

Submitted by loftarasa
loftarasa (1066016) writes "A group of scientists led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have developed a form of matter by binding massless photons together in a special kind of medium to create "photonic molecules", effectively bringing us a bit closer to a world with lightsabers.

"The discovery, Lukin said, runs contrary to decades of accepted wisdom about the nature of light. Photons have long been described as massless particles which don't interact with each other – shine two laser beams at each other, he said, and they simply pass through one another.

'Photonic molecules,' however, behave less like traditional lasers and more like something you might find in science fiction – the light saber.""
