Dispersion of the strongly correlated electron system near the Fermi level
arXiv:cond-mat/0108155
Abstract
The reason for the appearance of two distinct bands in the photoemission of the single CuO$_2$ plane Bi$_2$Sr$_{2-x}$La$_x$CuO$_{6+δ}$ near the Fermi level is discussed on the basis of the self-consistent solution of the two-dimensional t-J model.
