The polymers applied to the reflective surface - trap the photon gas in a parabola of light. The narrower this parabola is, the more one-dimensionally the gas behaves. © Artistic illustration: IAP/Uni Bonn all’images in original size .

Joint experiment by the University of Bonn and the University of Kaiserslautern-Landau

Physicists at the University of Bonn and the University of Kaiserslautern-Landau (RPTU) have created a one-dimensional gas out of light. This has enabled them to test theoretical predictions about the transition into this exotic state of matter for the first time. The method used in the experiment by the researchers could be used for examining quantum effects. The results have been published in the journal "Nature Physics."
