We consider the light in liters

Light flows like a river, and this is not a metaphor at all, Spanish physicists from the University of Vigo in the city of Orena say. With high intensity, a ray of light acquires properties, light. ” All these are physicists from the laboratory of Umberto Michinel whether he was able to observe during a unique computer experiment. With an increase in the intensity of the beam between the DE photons, energy arises like the one that acts between the molecules of conventional substances. And if the concentration is large enough, then the light can be brought to a dense, “liquid” state. Such conditions, for example, occurred in a bright flash from the explosion of the uranium bomb, the photon fluid at the same time exists only billions of a second. However, the “light river” can be made in a stationary, says Professor Michinel. To do this, he proposes to use “nonlinear media”: this is how the optics call materials that change their properties depending on the intensity of light. If the refractive index is reduced with an increase in intensity, then the photons from the core of the beam will be replaced by the periphery, and the beam comes into the “thin -walled pipe”. When the "walls" are quite thin, the light can become the same "dense" as in the outbreak of the atomic explosion.
