We present an exact diagonalization study of the dynamical spin and density correlation function of the 2D t-J model for hole doping < 25%. Both correlation functions show a remarkably regular, but completely different scaling behaviour with both hole concentration and parameter values: the density correlation function is consistent with that of bosons corresponding to the doped holes and condensed into the lowest state of the noninteracting band of width 8t, the spin correlation function is…

Approximate Decoupling of Spin and Charge Excitations in the Two-Dimensional t-J Model.
The single-particle spectral functions for the two-dimensional t - J model are investigated in connection with spin and charge dynamics, using the exact diagonalization technique. At low electron
Density fluctuations and phonon renormalization in the t-J model
Abstract The density response function of the t - J model is studied starting from a mixed gauge formulation of the slave boson approach. The theory predicts a low energy structure in a density
Spin and charge fluctuations in the t–J model
Abstract Dynamical spin and charge susceptibilities are calculated for the t – J model in the paramagnetic phase. Spin dynamics is scaled with the exchange interaction J and has a diffusive character
Density Response of Cuprates and Renormalization of Breathing Phonons
We analyse the dynamical density fluctuation spectra for cuprates starting from the t —J model in a slave-boson 1/N representation. The results obtained are consistent with diagonalization studies
Dynamic spin susceptibility in the t-J model
The dynamic spin susceptibility is calculated for the t-J model in the paramagnetic phase using the memory function method in terms of the Hubbard operators. A self-consistent system of equations for
Doping driven small-to-large Fermi surface transition andd-wave superconductivity in a two-dimensional Kondo lattice
We study the two-dimensional Kondo lattice model with an additional Heisenberg exchange between localized spins. In a first step we use mean-field theory with two order parameters. The first order

We present a theory for the lightly doped t-J model which is of possible relevance for the normal state of underdoped cuprates. Starting from an arbitrary dimer covering of the plane an exact
Spin fluctuations and high-temperature superconductivity in cuprates
Abstract To describe the cuprate superconductors, models of strongly correlated electronic systems, such as the Hubbard or t − J models, are commonly employed. To study these models, projected
Exact wave functions and excitation spectra of the one-dimensional double-exchange model with one mobile electron
Motivated by recent studies of the in-gap (or nonquasiparticle) states in the half-metallic ferromagnets, we study the one-dimensional double-exchange model with one mobile electron. We solve the
Dynamical domain walls and spin-Peierls order in doped antiferromagnets: Evidence from exact diagonalization of small clusters
The hole-doped two-dimensional(2D) t-J model is studied by exact diagonalization on a 5 × 4 cluster which, unlike the standard tilted-square clusters, can in principle accomodate an antiphase domain
