Electron 'pairing': Triplet superconductivity proven experientially for first time

Researchers have made the first experimental breakthrough in quantum physics: Their studies on the 'pairing behavior' of electrons have proven for the first time the existence of electron pairs, so-called Cooper pairs, with parallel spin direction. Cooper pairs cause superconductivity -- this is a particular state of material, in which the electrical resistance disappears. Until now the existence of triplet Cooper pairs has only been predicted theoretically.
