| dc.description | We study a one-dimensional p-d model with a finite bandwidth under the unrestricted Hartree-Fock approximation. It can be seen that charge fluctuations play an important role in the system, and the finite bandwidth will not qualitatively change the characteristics of the charge fluctuations. The appearance of the phase separation depends on the relative strength of the nearest-neighbour intersite Coulomb repulsion V<sub>pd</sub> The finite bandwidth turns the divergent behaviour of chi <sub>CT</sub> into a sharp peak in the curve of chi <sub>CT</sub> against epsilon . |
