Effects of Disorder on Coexistence and Competition between Superconducting and Insulating States
arXiv:cond-mat/0408457 · doi:10.1103/PhysRevB.71.224502
Abstract
We study effects of nonmagnetic impurities on the competition between the superconducting and electron-hole pairing. We show that disorder can result in coexistence of these two types of ordering in a uniform state, even when in clean materials they are mutually exclusive.
