Topologically ordered zigzag nanoribbon: e/2 fractional edge charge, spin-charge separation, and ground-state degeneracy
We numerically compute the density of states (DOS) of interacting disordered zigzag graphene nanoribbon (ZGNR) having midgap states showing e/2 fractional edge charges. The computed Hartree-Fock DOS is linear at the critical disorder strength where the gap vanishes. This implies an I-V curve of I∝V^...
