In the neutrinos» case, Cohen and Glashow calculate that the wake would mostly consist of electrons paired with their antimatter twins, positrons. (scientificamerican.com)
So figuring out what is keeping electron pairs together at nearly 40 K in MgB2 has become the latest contest in the most competitive area of materials physics. (sciencemag.org)
The effect appeared in a variety of transparent materials, says Jorio, and it was observed at room temperature, unlike electron pairing in superconductors. (sciencenews.org)
