Cuprate Superconductors - Where Are The Missing Electrons?

While there are still plenty of mysteries in electromagnetics, electrical engineers are sure of one thing; current is carried through materials by flowing electrons.  In physics, Luttinger's theorem states that the number of electrons in a material is the same as the number of electrons in all of its atoms added together. Much-studied conducting materials, such as metals and semiconductors, have held true to the idea.  read more
