Large size two - hole bound states in t - J model
نویسنده
چکیده
Several series of shallow large-size (l ≫ lattice spacing) two-hole bound states are found in the two-dimensional t−J model. Their binding energies depend exponentially on the inverse value of the hole-spin-wave coupling constant. Their parity is connected with the angular wave function in a nonstandard way. The possible role of these states in the formation of superconducting pairing is considered.

One- and two-hole states in the two-dimensional t-J model via series expansions
We study oneand two-hole properties of the t-J model at half-filling on the square lattice using series expansion methods at T50. The dispersion curve for one-hole excitations is calculated and found to be qualitatively similar to that obtained by other methods, but the bandwidth for small t/J is some 20% larger than given previously. We also obtain the binding energy and dispersion relation fo...

Asymmetric features of various physical quantities in the normal and superconducting states between hole- and electron-doped cuprate high-temperature superconductors have been an issue of debate for a long time. Their exploration is very important for the understanding not only of the mechanism of high-Tc superconductivity but also of the nature of doped-Mott insulators. Presented in this rev...

متن کاملSingle Hole Doped Strongly Correlated Ladder with a Static Impurity
We consider a strongly correlated ladder with diagonal hopping and exchange interactions described by t − J type hamiltonian. We study the dynamics of a single hole in this model in the presence of a static non-magnetic (or magnetic) impurity. In the case of a non-magnetic (NM) impurity we solve the problem analytically both in the triplet (S=1) and singlet (S=0) sectors. In the triplet sector ...
متن کاملHole pairs in a spin liquid: Influence of electrostatic hole-hole repulsion
The stability of hole bound states in the t-J model including short-range Coulomb interactions is analyzed using computational techniques on ladders with up to 2330 sites. For a nearest-neighbor ~NN! hole-hole repulsion, the two-holes bound state is surprisingly robust and breaks only when the repulsion is several times the exchange J . At ;10% hole doping the pairs break only for a NN repulsio...
