Description:
Phonons play two different roles in metals. At high temperatures, they scatter electrons, giving rise to electrical resistivity.At low temperatures, when a metal becomes a supeconductor, phonons bind pairs of electrons (Cooper Pairs), dropping the electrical resistance to zero. Phonons are a mathematical description of the vibrations of atoms in a crystal lattice. But are they real? That is, can they be detected outside the lattice in which they are supposedly created?n In the early 1970s, I
