From massless particles-photons can build physical objects - VIDEO PDF Print E-mail

The team of theoretical physicists at the National Institute of Standards and Technology (NIST) in the course of its new study showed how out of massless particles-photons can build physical objects. This work demonstrates that the particles of light can form a kind of "molecular" due to the action of special forces. The new study is a continuation of the work presented in 2013 a team of Mikhail LUKin. Then physicists presented a new method for binding the two photons in a "molecule": experimental demonstration was a real breakthrough in science, as earlier nobody has been able to combine the individual particles of light. Needless to say that serious fundamental development inspired by the famous Jedi lightsabers of the saga "star Wars." Knights "included" their swords and light blade arise out of nowhere, but it had a beginning and an end, and therefore, it is material. Papers accepted for publication in the journal Physical Review Letters, describes how the experimental method can be achieved by forming the photonic molecule that will form the basis of the legendary light of the matter. Now the material is available online preprints arXiv.org. Scientists say that by setting a few parameters of the process of binding the particles of light photons can be made to extend side-by-side with each other, and they will be just the same on a certain distance from each other. This configuration may be compared to the behavior of the two hydrogen atoms in the molecule. "It's hard to call a complete molecule. However, the configuration of the photons in the described contact structure is very similar to the configuration of atoms in this molecule. At the moment, we are studying various states of light, to subsequently learn how to build more complex objects. But now we can say that we have get two photons propagate at a fixed distance from each other, "- says the lead author of the new study Alexei Gorshkov. The main obstacle on the way to building a full-fledged subject of light "molecules" - is the need to respect a number of harsh environmental conditions, under which only the photons will be distributed "holding" for each other. But if before the creation of the Jedi lightsaber still far away, today physicists understand how you can use a light matter. "A lot of modern technologies based on light - from communications technology to the high-resolution imaging. And all of these technologies can be significantly improved if learn how to manage interactions between photons" - says Gorshkov. Researchers promise to continue to work in this direction and hope that one of the lightsaber formed a queue at their laboratory.
