    • The nondegenerate ground state with a total spin of zero and a total momentum of zero is obtained when BC is chosen to form the closed-shell configuration in momentum space.

    • + is exactly that for the one-hole system which is considered to be different from a system with a finite number of holes. We thus discuss only A_.

    • note
    • Antiperiodic BC is used to form the closed-shell configuration. To guarantee that the ground state has a total momentum of zero, we introduce the next-nearest-neighbor hopping of t′ = -0.1t.
