Title: Enhancement of superconductivity by frustrating the charge order

Abstract

We study strong electron-phonon interacting systems where the geometry of the crystalline lattice frustrates the formation of charge order. Here, our results show that under such condition, high-Tc superconductivity can occur in a wide range of electron-phonon coupling strengths. This result is obtained by studying the Holstein model on triangular lattice using sign-problem-free quantum Monte Carlo method.
