A research team led by the University of Osaka has directly observed, for the first time, an unusual heavy-fermion state forming at the boundary between a one-atom-thick material and a metal. Such states are closely linked to exotic quantum phenomena, including unconventional superconductivity, and the finding opens new possibilities for designing quantum materials through their

Black holes, despite their extreme nature, are described by surprisingly few basic parameters: their mass, charge and spin. Two black holes may have formed for completely different reasons and passed through very different histories, yet still end up in the same final state. John Wheeler summarized this idea with the famous phrase “black holes have
