Forscher beobachten Quantenstrudel in kalten Helium-Tröpfchen

Nanotropfen rotieren schneller als erlaubt

(PresseBox) (Hamburg, )
Ein internationales Forscherteam unter Beteiligung von DESY-Forschern hat winzige Quantenstrudel in kalten Tröpfchen aus flüssigem Helium beobachtet. Die exotischen Strudel ordnen sich in den Nanotröpfchen zu dichtgepackten Gittern, wie das Team im US-Fachblatt "Science" berichtet. Es ist das erste Mal, dass die Quantenstrudel, die bereits in größeren Proben von sogenanntem supraflüssigen Helium gesichtet worden sind, in Nanotröpfchen nachgewiesen wurden. "Das Experiment hat unsere höchsten Erwartungen übertroffen", betont Andrey Vilesov von der Universität von Südkalifornien, einer der drei Leiter des Experiments.

Das Edelgas Helium wird bei minus 269 Grad Celsius flüssig. Unterhalb von minus 271 Grad tritt ein Quanteneffekt auf, klqzc wnf vjt ptagaudi Nvunrd fkph jcystn Pnmympp ccrqjcds, iv bgdf lvwowzeevboa.
