Redistribution of the hole spectral weight due to long-range spin correlations in the three-band Hubbard model
Barabanov A.F., Maksimov L.A., Z&acedil;sinas E., Urazaev O.V.
In the framework of the three-band model for óÉïÇ plane in high-temperature superconductors the spectrum of the spin-polaron hole exitation is investigated. The problem is treated taking into account the coupling of a local polaron with the antiferromagnetic spin wave with Q ~ (ίγ, 7r).This leads to the essential changes of the lowest polaron band e\ (k) and the strong redistribution of the bare electron filling.
