RPES of the Electron-Doped Cuprates Studied by the Variational Monte-Carlo Method

We use a variational approach to gain insight into low-energy states of extended $t-J$ model in the electron-doped regime. Compared with the recent results on $Nd_{1.87}Ce_{0.13}CuO_{4}$ obtained by ARPES, we show that strong correlations lead to qualitatively similar trends in ARPES spectra and Fermi surface topology. Additionally, the results about Fermi surface evolution as a function of doping density will be discussed.
