In most superconductors, the pairing-up of electrons responsible for resistance-less conduction is driven by vibrations of the solid's crystal lattice. But other materials exist in which the attractive interaction responsible for binding electrons is believed to have a very different origin: quantum fluctuations of spin or charge. This paper identifies an unusually 'violent' generalization of such pairing mechanisms, in which these spin and charge instabilities combine forces.
