Figure 3
The response I(q, Ω) obtained with DMRG for a multi-orbital pd model as a function of the number of CuO4 plaquettes. Panels (a–f) show the spin-conserving ΔS = 0 channel of the RIXS intensity, while panels (g–l) show the non-spin-conserving ΔS = 1 channel. Results are shown for 8 to 20 unit cells at half filling, computed at resonance with ωin = 2.5, Γ = 0.2, and VC = 4.0 (in eV units).
