One of the first theoretical proposals for understanding high-temperature superconductivity
in the cuprates was Anderson's RVB theory using a Gutzwiller projected BCS wavefunction …

We review the resonating valence bond (RVB) theory of high-temperature superconductivity
using Gutzwiller projected wave functions that incorporate strong correlations. After a …

While density matrix renormalization group calculations find stripes on doped n-leg tJ
ladders, little is known about the possible formation of stripes on n-leg Hubbard ladders …

The authors discuss concepts used by them and others for studying high temperature
superconductivity. These shed some light on basic questions. Suggestions are presented …

It is shown, using asymptotically exact methods, that the two-dimensional repulsive Hubbard
model with strongly modulated interactions exhibits “high-temperature superconductivity.” …

We investigate the effects of the next-nearest-neighbor (t′) and the third-nearest-neighbor
(t′′) hopping terms on superconductivity correlation in the 2D hole-doped extended tJ …

We investigate the formation of stripes in 7 r× 6 Hubbard ladders with 4 r holes doped away
from half filling using the density-matrix renormalization group (DMRG) method. A …

A connection between quantum antiferromagnetism and high T c superconductivity is
theoretically investigated by analyzing the tJ model and its relationships to the Gutzwiller …

We have calculated high temperature series to 12th order in inverse temperature for singlet
superconducting correlation functions of the 2D tJ model with s, dx 2-y 2, and dxy symmetry …

The mechanism of high-temperature superconductivity (HTS) and the correlation between
the antiferromagnetic long-range order (AFLRO) and superconductivity (SC) are the central …
