New disordered anyon phase of doped graphene zigzag nanoribbon
Young Heon Kim, Hye Jeong Lee, Hyng-Yong Lee +1
We investigate interacting disordered zigzag nanoribbons at low doping, using the Hubbard model to treat electron interactions within the density matrix renormalization group and H…
Topological entanglement entropy of interacting disordered zigzag graphene ribbons
Young Heon Kim, Hye Jeong Lee, S. -R. Eric Yang
Interacting disordered zigzag graphene nanoribbons have fractional charges, are quasi-one-dimensional, and display an exponentially small gap. Our numerical computations showed tha…
Topologically ordered zigzag nanoribbon: fractional edge charge, spin-charge separation, and ground state degeneracy
S. -R. Eric Yang, Min-Chul Cha, Hye Jeong Lee +1
We numerically compute the density of states (DOS) of interacting disordered zigzag graphene nanoribbon (ZGNR) having midgap states showing fractional edge charges. The compu…
