Prediction of the in-Gap States Above the Top of the Valence Band in the Undoped Insulating Cuprates due to Spin-Polaron Effect

S. G. Ovchinnikov, A. A. Borisov, V. A. Gavrichkov +1

In the framework of the generalized tight binding method we have calculated the quasiparticle band structure and the spectral functions of the undoped cuprates like $L{a}_{2}Cu{O}_4$, $…
