Superconductivity in high-Tc cuprates: ‘from maximal to minimal dissipation’ – a new paradigm?

Researchers used some of Europe’s strongest continuous magnetic fields to uncover evidence of exotic charge carriers in the metallic state of copper-oxide high-temperature superconductors (high-Tc cuprates). The team postulated that it is these exotic charge carriers that form the superconducting pairs, in marked contrast with expectations from conventional theory.
