Abstract:
We describe the static charge susceptibility and correlation function of the charge density in the two-dimensional $t$–$J$–$V$ model based on the method of equations of motion for the relaxation functions of the Hubbard operators. We obtain the dependence of the susceptibility and correlation function on the hole concentration and temperature. Charge density waves can develop if the intersite Coulomb interaction is sufficiently strong.
Keywords:
strong electron correlation, charge susceptibility,
high-temperature superconductivity, $t$–$J$–$V$ model.
