Bad Metals
Metals conduct electricity because they contain electrons that are free to move through the material. In bad metals the electrons seem to reversibly disappear and reappear. ~ American solid-state physicist Rafael Jaramillo
Theoretically, the hotter the metal, the worse it conducts electricity. Most metals obey this inverse relationship between temperature and conductivity. But some do not. These conductive miscreants are termed bad metals.
At high temperatures, the electrons in bad metals ought to violate Heisenberg’s uncertainty principle, rendering them nonconductive. But they refuse to bow to uncertainty. Instead, bad metals invoke extra-dimensional effects to keep their electrons flowing.
Electron-electron interactions are so strong in bad metals. ~ American physicist Ray Osborn
