Machine-learning test of the single-ion model for $dd$ excitations in cuprates

Maryia Zinouyeva, Leonardo Martinelli, Riccardo Arpaia +12

We investigate $dd$ excitations in Resonant Inelastic X-ray Scattering spectra of YBa${}_2$Cu${}_3$O${}_6$ and La${}_2$CuO${}_4$ using the local single-ion model. The data are analyzed by co…
