Half-skyrmion picture of single hole doped high-T_c cuprate
arXiv:cond-mat/0502437 · doi:10.1016/j.jmmm.2005.09.042
Abstract
The single hole doped CuO_2 plane is studied by the O(3) non-linear σmodel and its CP^1 representation. It is argued that the spin configuration around a Zhang-Rice singlet is described by a half-skyrmion. The form of the excitation spectrum of the half-skyrmion is the same as that in the π-flux phase.
