  The interplay between electron-electron correlations and disorder has been a
central theme of condensed matter physics over the last several decades, with
particular interest in the possibility that interactions might cause
delocalization of an Anderson insulator into a metallic state, and the
disrupting effects of randomness on magnetic order and the Mott phase. Here we
extend this physics to explore electron-phonon interactions and show, via exact
quantum Monte Carlo simulations, that the suppression of the charge density
wave correlations in the half-filled Holstein model by disorder can stabilize a
superconducting phase. Our simulations thus capture qualitatively the
suppression of charge ordered phases and emergent superconductivity recently
seen experimentally.
