Query: Variational Monte Carlo simulation in hole-doped cuprate
  superconductors: Competition between antiferromagnetism and superconductivity   We present variational Monte Carlo (VMC) results for the Gutzwiller-projected
coexisting state including both antiferromagnetic (AFM) order and
superconducting (SC) order in the two-dimensional t-t'-t"-J model. By further
considering off-site spin correlation between electrons, in contrast to earlier
VMC results [Phys. Rev. Lett. 102, 027002 (2009)], we find the apparent
competition between AFM order and SC order near the underdoped regime instead
of coexistence. The local ferromagnetic correlation introduced by spin-spin
Jastrow correlators seem to be responsible for the disappearance of the
coexisting state. We also demonstrate that the quasiparticle spectral weight
from upper (lower) AFM band are strongly diminished (enhanced) by the spin-spin
correlation. This result obviously leads to the loss of antinodal electron
pockets and the appearance of nodal hole pockets as passing from the AFM phase
to the SC phase in hole-doped cuprates, which is in consistent with the
observation by angle-resolved photoemission spectroscopy.
