Topics: Condensed Matter Physics, Materials Science, Modern Physics, Superconductors It’s one of the most stubborn open questions of modern physics: What’s the mechanism of high-temperature superconductivity? All superconductors need some way of binding their electrons, which are fermions, into quasiparticles called Cooper pairs, which act as bosons. The low-temperature superconductivity in metals is well describedContinue reading “Superconductivity and Electron Pairs…”
