Science creates the „Matter of Lightsabers“

Wissenschaftler haben Photonen (Lichtteilchen) auf knapp über den Nullpunkt runtergefrohrene Atome gefeuert und dabei eine neue Materieform geschaffen: Lichtmoleküle. Die Photonen werden bei dem Vorgang aufgrund des Energieaustauschs mit den Atomen so weit runtergebremst, dass sie eine „Materie aus Licht“ formen. Prof. Mikhail Lukin hält den Vergleich mit Lichtschwertern für nicht unangebracht. In der Realität wird die Entdeckung vor allem bei der Entwicklung von Quantencomputern helfen, auf Lichtschwerter dürften wir noch 'ne Weile warten.

"Photonic molecules," however, behave less like traditional lasers and more like something you might find in science fiction – the light saber.

"Most of the properties of light we know about originate from the fact that photons are massless, and that they do not interact with each other," Lukin said. "What we have done is create a special type of medium in which photons interact with each other so strongly that they begin to act as though they have mass, and they bind together to form molecules. This type of photonic bound state has been discussed theoretically for quite a while, but until now it hadn't been observed.

"It's not an in-apt analogy to compare this to light sabers," Lukin added. "When these photons interact with each other, they're pushing against and deflect each other. The physics of what's happening in these molecules is similar to what we see in the movies."
