Query: Low-energy Spectra of the t-J-Type Models Studied by Variational
  Approach   We discuss recent progress of understanding the phenomena observed in high Tc
cuprates by studying the d-wave resonating-valence-bond (d-RVB) based trial
wave functions for the 2-dimensional t-J-type models. Treat exactly the strong
correlation between electrons by numerical approach, we examine the evolution
of ground states described by different variational wave functions and
properties of the quasi-hole and -particle excitations of the d-RVB
superconducting (SC) state. Properties related to the Fermi surface geometry
deduced from quasi-hole energy dispersion of the SC state is shown to be
consistent with the observation by photoemission spectroscopy. With the
calculated spectral weights (SW's) for adding and removing an electron, we
found not only the anti-correlation between conductance peak height and width
between peaks seen in tunneling experiments, but also unique properties due to
strong correlation which need to be verified by future experiments.
