We consider a massless fermion interacting with the gauge field by Pauli interaction in which the coupling constant is dimensionless. The model is equivalent to the s=1/2 antiferromagnetic XXZ spin chain. The two flavours massless fermion of such model can describe the two-leg spin ladder system qualitatively, and there is no gapless exitation in such a system.
