Query: The electronic pseudogap in optimally doped NCCO   We study the effect of antiferromagnetic correlations in the three-band Emery
model, in comparison with the experimental angle-resolved photoemission (ARPES)
spectra in optimally doped NCCO. The same calculation, formerly used to
describe BSCCO, is relevant here, but in contrast to BSCCO, where quantum
paramagnon fluctuations are important, the characteristic energy of the
dispersive paramagnons in NCCO is of the order of Tc. The wide dispersing
features of the single-electron spectrum in NCCO are analogous to the BSCCO
hump. The Fermi surface is pseudogapped in both the nodal and antinodal
directions, although the detailed features differ, being dominated by loss of
intensity in the nodal direction, and loss of coherence in the antinodal one.
Direct oxygen-oxygen hopping is important in NCCO as well as in BSCCO, in order
to obtain overall agreement with the measured ARPES spectra.
