Universal power-law behavior of local electron correlation functions in the Falicov–Kimball lattice model

Yu-Liang Liu

By studying the Falicov--Kimball lattice model, we demonstrate that the correlation functions of local electrons can be written directly in the form of the partition function of conduction electrons with a time dependent external potential. These general expressions of the correlation functions are equivalent to the exact ones obtained by the dynamical mean field theory in infinite dimension limit. Moreover, we also prove that the asymptotic power-law behavior of the local electron correlation functions is universal in any dimensions, as long as the conduction electron excitation spectrum is gapless, regardless whether they are Landau Fermi liquid or not. This conclusion is also valid for other quantum many-particle systems, if the coupling between the conduction and local electrons is on-site or short-range Coulomb interaction.

Dynamic Susceptibility of 1D Conductors: The Short-Range Electron Correlation Effect

Vladimir A. Sablikov, Yasha Gindikin

The dynamic density response and susceptibility of interacting electrons in 1D conductors is investigated taking into account the electron correlations reflecting the short-range order in a Luttinger liquid. We have shown that a narrow band of strong absorption appears in the dissipative susceptibility spectrum near to the wave vector 2kp due to the short-range correlations in addition to the commonly known delta-peak coming from the long-wave fluctuations. The adsorption band shape depends on the electron-electron interaction potential. This band is found to contribute dominantly to the dissipative conductance determined via the power absorbed in 1D conductor under local excitation.
