Normal Fermi Liquid Behavior of Quasiholes in the Spin-Polaron Model for Copper Oxides

Abstract

Based on the t-J model and the self-consistent Born approximation, the damping of quasiparticle hole states near the Fermi surface is calculated in a low doping regime. Renormalization of spin-wave excitations due to hole doping is taken into account. The damping is shown to be described by a familiar form $\text{Im}\Sigma ({\mathbf{k}}^{\prime },\epsilon )\propto ({\epsilon }^2/{\epsilon }_F)\ln (\epsilon /{\epsilon }_F)$ characteristic of the 2-dimensional Fermi liquid, in contrast with the earlier statement reported by Li and Gong [Phys. Rev. B {\bf 51}, 6343 (1995)] on the marginal Fermi liquid behavior of quasiholes.
