Excitations in the charge ordered state of one-dimensional extended Hubbard model at half-filling
Source abstract
Abstract
We investigate excitation spectra in the charge ordered state of the one-dimensional extended Hubbard model at half-filling with taking account of fluctuations around the mean-field solution. The imaginary parts of the dynamical susceptibilities, the dispersion relations and the weights of the collective modes are discussed.
