Physicists generate light consisting of a new form

Physicists generate light consisting of a new form. To experiment, if you take two flashlights into a darkroom and make their beams cross. Will they yield any result, in fact no because individual photons that comprise light do not interact. They pass by each other like mediocre spirits in the night.

However, the thought that light particles could interact enticing and repulsing each other like atoms in customary matter cannot be neglected. Light sabers are that beams of light which can pull and push on each other, representing impressive epic conflict. Or in a feasible scenario two beams of light could encounter and consolidate into one single brilliant stream.

It looks as if such an optical conduct would require stretching the rules of physics to an extreme.  However, scientists at MIT, Harvard and elsewhere have now illustrated that photons can be made to interact, an achievement that could lead the way to usage of photons in quantum computing, if not in light sabers.

In a paper published in the journal Science the team, led by Vladan Vuletic, the Lester Wolfe Professor of Physics at MIT, and Professor Mikhail Lukin from Harvard University, states that it has seen groups of three photons combining and to a large extent sticking together to contemplate an entirely novel kind of photonic matter.

In checked experiments, the researchers discovered that when they gleamed an extremely weak laser beam through a heavy cloud of ultra-cold rubidium atoms, rather than going of cloud as single random photons, the photons clubbed together as pairs or triplets proposing some kind of interaction taking place among them.
