In the Wigner-Jordan (WJ) fermion representation of quantum spins with antiferromagnetic interaction, the WJ fermions always fill half of the total available states, and their energy spectrum possesses a particle-hole symmetry. These two intrinsic properties of the WJ representation, together with a finite density of states at small WJ-fermion excitation energy, give rise to the marginal-Fermi-liquid behavior of the charge carriers when they are scattered by the WJ fermions. The finite density of states of the WJ fermions at zero excitation energy is demonstrated for the defected quantum antiferromagnetic Heisenberg model in a square lattice.
