Redistribution of the Hole Spectral Weight due to Long-Range Spin Correlations in the Three-Band Hubbard Model

In the framework of the three-band model for CuO_2 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=(pi,pi). This leads to...

Description
Summary:	In the framework of the three-band model for CuO_2 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=(pi,pi). This leads to the essential changes of the lowest polaron band E(k) and the strong redistribution of the bare electron filling.
