<i>d</i>-wave superconductivity from electron-phonon interactions
Abstract
I examine electron-phonon mediated superconductivity in the intermediate coupling and phonon frequency regime of the quasi-two-dimensional Holstein model. I use an extended Migdal-Eliashberg theory that includes vertex corrections and spatial fluctuations. I find a <i>d</i>-wave superconducting state that is unique close to half filling. The order parameter undergoes a transition to <i>s</i>-wave superconductivity on increasing filling. I explain how the inclusion of both vertex corrections and spatial fluctuations is essential for the prediction of a <i>d</i>-wave order parameter. I then discuss the effects of a large Coulomb pseudopotential on the superconductivity (such as is found in contemporary superconducting materials like the cuprates), which results in the destruction of the <i>s</i>-wave states, while leaving the <i>d</i>-wave states unmodified.
