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…”

Scandium and Superconductors…
Scandium is the only known elemental superconductor to have a critical temperature in the 30 K range. This phase diagram shows the superconducting transition temperature (Tc) and crystal structure versus pressure for scandium. The measured results on all the five samples studied show consistent trends. (Courtesy: Chinese Phys.

Superconductors, 3D Disorder, Fractals…
Fractals are a never-ending pattern that you can zoom in on, and the image doesn’t change. Fractals can occur in two dimensions, like frost on a window, or in three dimensions, like the limbs of a tree. A recent discovery from Purdue University researchers has established that superconducting images, seen above in red and blue,Continue reading “Superconductors, 3D Disorder, Fractals…”
