In recent years, much attention has been attracted to the 1D strong correlated system with two mechanisms of opening gaps. The models include:(1) the frustrated spin-Peieds system,(2) the 1D Hubbard model with a staggered potential,(3) the antiferromagnetic Heisenberg chain with Dzyaloshinskii—Moriya interaction,(4) the spontaneously dimerized s=1/2 antiferromagnetic chain in a staggered magnetic field.
