The phase diagram of the planar t--J model at small hole doping is investigated by finite size scaling of exact diagonalisation data of NXN clusters (up to 26). Hole-droplet binding energies, compressibility and static spin and charge correlations are calculated. Short range antiferromagnetic correlations can produce attractive forces between holes leading to a very rich phase diagram including a liquid of d-wave hole pairs (for $J/t\gtrsim 0.2$), a liquid of hole droplets (quartets) for larger…

Phase diagram for a t-J bilayer: role of interlayer couplings
AbstractThe phase diagram for a t-J bilayer as a function of interplanar hopping, t⊥ and hole concentration, x is presented for a few different values of interplanar exchange, J⊥ using variational
Phase Diagram and Pairing Symmetry of the Two-Dimensional t-J Model by a Variation Theory
Two-dimensional t - J model is studied by a variational Monte Carlo method, using Gutzwiller-Jastrow-type wave functions. Various kinds of superconducting pairing symmetries are compared in order to
Phase Separation in the Two-Dimensional Systems of Strongly Correlated Electrons: The Role of Spin Singlet Pairs on Hole Pairing Contribution to Hole-Rich Phase
By paying attention to the hole-doped two-dimensional systems of antiferromagnetically (strongly) correlated electrons, we discuss the cause of hole-rich phase formation in association with phase
Investigation of charge stripe formation in an extended t–J model
We consider a possible mechanism of the charge stripes in the high-Tc cuprates, based on some additional interactions in the two-dimensional t–J model; the next-nearest-neighbour and/or four-spin
Finite compressibility in the low-doping region of the two-dimensional t-J model
We reexamine the important issue of charge fluctuations in the two-dimensional $t\text{\ensuremath{-}}J$ model by using an improved variational method based on a wave function that contains both
The t–J model for the oxide high-Tc superconductors
A theoretical review is given on high temperature superconductivity in copper oxides (cuprates) by focusing on the hole doping cases based on the view that it is realized in carrier doped Mott
Green’s-function Monte Carlo for lattice fermions: Application to the t − J model
We develop a general numerical method to study the zero temperature properties of strongly correlated electron models on large lattices. The technique, which resembles Green’s Function Monte Carlo,
