Abstract
All the eigenfunctions with spin of one-dimensional half-filled Hubbard model are obtained by using a simple method ( is the number of the sites). These eigenfunctions depend on , and the momentum . It is shown that the eigenstates we obtained can describe varioue kinds of pseudospin waves with wave vector and these pseudospin wave states are accompanied with a charge transferring. This is in agreement with the exact diagonalization results for small sites ring.
