Query: Quasiparticle spectral weights of Gutzwiller-projected high T_c
  superconductors   We analyze the electronic Green's functions in the superconducting ground
state of the t-J model using Gutzwiller-projected wave functions, and compare
them to the conventional BCS form. Some of the properties of the BCS state are
preserved by the projection: the total spectral weight is continuous around the
quasiparticle node and approximately constant along the Fermi surface. On the
other hand, the overall spectral weight is reduced by the projection with a
momentum-dependent renormalization, and the projection produces electron-hole
asymmetry in renormalization of the electron and hole spectral weights. The
latter asymmetry leads to the bending of the effective Fermi surface which we
define as the locus of equal electron and hole spectral weight.
