Single hole dispersion relation for the real CuO$_2$ plane

Condensed Matter 2009-10-28 v2

Abstract

Dispersion relation for the CuO2_2 hole is calculated basing on the {\it generalized} tt-tt^{\prime}-JJ model, recently derived from the three-band one. Numerical ranges for all model parameters, t/J=2.4..2.7t/J=2.4..2.7, t/t=0..0.25t^{\prime}/t = 0..-0.25, t/t=0.1..0.15t^{\prime\prime}/t=0.1..0.15, and three-site terms 2tNtSJ/42t_N\sim t_S\sim J/4, have been strongly justified previously. Physical reasons for their values are also discussed. Self-consistent Born approximation is used for the calculation of the hole dispersion. An excellent agreement between calculated EkE_{\bf k} and one obtained from the angle-resolved photoemission experiments is found.
