Scientists from Universität Hamburg and the Cluster of Excellence "CUI: Advanced Imaging of Matter" have succeeded in observing strong evidence of superfluidity in a central model system, a two-dimensional gas cloud for the first time

Zero electrical resistance at room temperature? A material with this property, i.e. a room temperature superconductor, could revolutionize power distribution. But so far, the origin of superconductivity at high temperature is only incompletely understood. (...) For the first time, the scientists in Prof. Henning Moritz's group have succeeded in observing Josephson oscillations in a two-dimensional (2-D) Fermi gas. These Fermi gases consist of a "breath of nothing," namely a gas cloud of only a few thousand atoms. Saiba mais...
