Diagonal superexchange in a simple square CuO lattice
V. A. Gavrichkov, S. I. Polukeev, S. G. Ovchinnikov
Many microscopic models with the interaction between the next-nearest neighbours as a key parameter for cuprate physics have inspired us to study the diagonal superexchange interac…

In-gap excitation effect on a superexchange in La2CuO4 by creating nonequilibrium photoexcited centers
Vladimir A. Gavrichkov, Semen I. Polukeev, Sergey G. Ovchinnikov
We propose a multielectron approach to calculate superexchange interaction in magnetic Mott- Hubbard insulator La2CuO4(further La214) that allows to obtain the effect of optical pu…
