Nonmonotonic d_{x^2-y^2}-Wave Superconductivity in Electron-Doped Cuprates Viewing from the Strong-Coupling Side

Tsutomu Watanabe, Takafumi Miyata, Hisatoshi Yokoyama +2

Applying a variational Monte Carlo method to a two-dimensional t-J model, we study the nonmonotonic d_{x^2-y^2}-wave superconductivity, observed by Raman scattering and ARPES exper…
