Backward Scattering and Coexistent State in Two-Dimensional Electron System
arXiv:cond-mat/9802009 · doi:10.1143/JPSJ.67.2784
Abstract
The results of the mean field studies on the effects of the backward scattering with large momentum transfer in a two-dimensional electron system are extended to the case with various types of the Fermi surface and coupling constants. It is found that the coexistent state of d-wave superconductivity, antiferromagnetism and -triplet pair can be stabilized quite generally near half filling.
