Thanks to high resolution and polarization analysis, resonant inelastic x-ray scattering (RIXS) magnetic spectra of La2CuO4, Sr2CuO2Cl2 and CaCuO2 reveal a rich set of properties of the spin 1/2 antiferromagnetic square lattice of cuprates. The leadi

The optical conductivity σ(ω) of undoped and very low doped YBa2Cu3O6.0δ is studied in detail in the midinfrared range. We collect experimental evidence for a magnetic origin of the observed absorption. The main resonance peak is well described by

We discuss two-magnon phonon-assisted infrared absorption in two-dimensional Heisenberg systems like the parent insulating high-T-c cuprates (spin 1/2) and nickelates (spin 1). The theoretical line shape is compared with experiments. In the case of t

We present estimates in the Hubbard and Heisenberg models for the spectral weight in magnetic neutron-scattering experiments on the cuprates. With the aid of spin-wave theory and the time-dependent Gutzwiller approximation, we discuss how the spectra
