Interrelation between Doping Dependencies of the Spin Susceptibility and Electronic Structure in Cuprates

https://doi.org/10.1134/S0021364024601945

We calculate electronic structure and spin susceptibility dependencies on doping within the framework of a cluster perturbation theory for strongly correlated electronic systems. The change in the susceptibility with increasing doping is qualitatively consistent with the experimental data on resonant inelastic X-ray scattering and inelastic neutron scattering, as well as with the results of the calculations within the quantum Monte Carlo method.
