ELECTRON CORRELATION FUNCTIONS FOR NEUTRAL SOLITON
中性孤子的关联函数

The electron correlation functions in spin-nondegenerate systems are studied in this paper. By using Hartree-Fock approximation, we present the spin-dependent electron correlation functions for neutral soliton, where there is only one up-spin electron on the mid-gap state. We obtain the pictures of spin-dependent correlation functions and discuss their properties.
