Hole Superconductivity in MgB2, Cuprates, and Other Materials
J. E. Hirsch
Abstract
The theory of hole superconductivity proposes that MgB2, and the high Tc cuprates, and the 'conventional superconductors', and all other superconductors, are driven by the same physical mechanism, which is not the electron-phonon interaction. That mechanism, hole undressing, evidence supporting it, and predictions for MgB2, are briefly reviewed.
