Dispersion of the dielectric function of a charge-transfer insulator
R. O. Kuzian, R. Hayn, A. F. Barabanov
We study the problem of dielectric response in the strong coupling regime of a charge transfer insulator. The frequency and wave number dependence of the dielectric function $ε({\b…

Recursion method and one-hole spectral function of the Majumdar-Ghosh model
R. O. Kuzian, R. Hayn, J. Richter
We consider the application of the recursion method to the calculation of one-particle Green's functions for strongly correlated systems and propose a new way how to extract the in…
