a Schematics of the non-interacting electronic structure of the low-energy effective model Eq. (1) where Eds is the energy separation between the bare energy of Ni-\({d}_{{x}^{2}-{y}^{2}}\) and effective-s orbitals. b The total energy (up to a constant) of the PM (red), the AFM (blue) and the CO (green) states as a function of Eds, calculated by using the low-energy effective model Eq. (1) with Ud = 3.7 eV. The orange dashed line highlights Eds = 0.7 eV, which is obtained from fitting to the DFT band structure of NdNiO2. c The total energy of different stripe CO states with the wavevector \({{{{{{{\bf{q}}}}}}}}=\left(\frac{1}{N},\, 0,\, 0\right)\) as a function of Ud, calculated by using the low-energy effective model Eq. (1) with Eds = 0.7 eV. d The total energy of different stripe CO with the wavevector \({{{{{{{\bf{q}}}}}}}}=\left(\frac{1}{N},\, 0,\, 0\right)\) as a function of Eds, calculated by using the low-energy effective model with Ud = 3.7 eV. In panels (b–d), the error bar is smaller than the symbol size (see Methods). Source data are provided as a Source Data file.
