摘要：

We study magnetic and charge order in the electron-doped high-Tc cuprates based on the one-band Hubbard model with onsite U and nearest-neighbor V interactions. To investigate the interplay between the orders, we employ the Kotliar-Ruckenstein slave-boson method and analyze fluctuations descending from an antiferromagnetic parent state. Our analysis reveals incommensurate charge order whose ordering vector matches the doping dependence of resonant inelastic x-ray scattering (RIXS) measurements in Nd2-xCexCuO4 (NCCO). From our calculations of paramagnon dispersion as well as dynamical charge and spin structure factors, we reproduce the characteristic features of the RIXS signal.
