Superconductors usually lose their ability to transport electricity without electrical resistance at too high current. With only about two picoseconds of long pulses, physicists have significantly exceeded this usual limit in niobnitride. The electron pairs decisive for superconductivity disintegrated only at about 2.2 times the conventional critical current density. In a second material, however, the transition went [...] The article Supercondu…
