Query: Common origin of the pseudogap in electron-doped and hole-doped cuprates
  governed by Mott physics   The pseudogap phenomena have been a long-standing mystery of the cuprate
high-temperature superconductors. Unlike the pseudogap in hole-doped cuprates,
however, the pseudogap in the electron-doped counterpart has been attributed to
band folding due to short-range antiferromagnetic (AFM) order. We performed
angle-resolved photoemission spectroscopy measurements on electron-doped
cuprates showing spin-glass and disordered AFM behaviors at low temperatures,
and found that the gap magnitude \textit{decreases} in the antinodal region
contrary to the hole-doped case. Moreover, the gap opening position was not
always on the AFM Brillouin zone boundary in contradiction with the requirement
of the AFM band-folding picture. These features are consistent with cluster
dynamical-mean-field-theory calculations which predict an $s$-symmetry
pseudogap that shrinks in the andinodal region. The present results support the
scenario that the proximity to the Mott insulator, without relying on the
well-developed AFM correlation, gives rise to a momentum-dependent pseudogap of
$s$-symmetry with indirect gap commonly in the electron-doped and hole-doped
cuprates, implying a universal origin of the pseudogap with a similarity to the
Mott gap formation.
