Superconductivity in cuprates: maximal to minimal dissipation - a new paradigm?
Superconductivity in cuprates: ‘from
maximal to minimal dissipation’ - a new
paradigm?
Researchers from the School of Physics 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). Their results have been published last week in Nature [1]. In a related
publication in SciPost Physics the week before [2], members from the same
team postulated that it is these exotic charge carriers that form the
superconducting pairs, in marked contrast with expectations from conventional
theory.
