Rupture of a Photon Dam

par Webmestre - publié le

« If the intensity of a light pulse is high enough, photons in the pulse can interact and behave like molecules in a fluid. Fluid-like phenomena such as rogue waves, superfluidity, and turbulence have all been observed in light pulses. Now, a team of scientists from the University of Lille, France, and the University of Ferrara, Italy, has induced photon behavior reminiscent of that seen in water flow following the collapse of a dam. According to the researchers, their experimental setup could be used to explore optical counterparts of other fluid phenomena that involve fast changes in the photon flow of propagating light pulses, such as the shock generated when a moving piston compresses a gas... »
