Stuttgarter Physiker vermessen Grenze zwischen stabilen und instabilen Zuständen von Quantengasen aus Magneten

(PresseBox) (Stuttgart, )
Instabilitäten von sich anziehender Materie sind in der Astrophysik seit langem bekannt und führen zu so spektakulären Ereignissen wie einer Supernova. Auch ein Gas aus lauter kleinen atomaren Magneten ist nicht stabil. Es implodiert durch die anziehende Wechselwirkung zwischen den Magneten. Die Forschergruppe von Prof. Tilman Pfau am 5. Physikalischen Institut der Universität Stuttgart hat nun das komplette Stabilitätsdiagram, das heißt die Grenze zwischen stabilen und instabilen Zuständen eines Quantengases aus Magneten vermessen und die Ergebnisse in der jüngsten Ausgabe von Nature Physics publiziert.*)
