Superconductivity in the presence of strong electron-phonon interactions and frustrated charge order
arXiv:1812.10263 · doi:10.1103/PhysRevB.100.245105
Abstract
We study the superconductivity of strongly coupled electron-phonon systems where the geometry of the lattice frustrates the charge order by the sign-problem-free Quantum Monte Carlo(QMC) method. The results suggest that with charge order frustrated, the superconductivity can benefit from strong electron-phonon interaction in a wide range of coupling strengths.
