Fig. 4: The band structure, local bond current distribution and probability distribution for antichiral edge states.
From: Modulation of antichiral edge states in zigzag honeycomb nanoribbons by side potentials
a The band structure of one case of Type-1 with U1 = 0.2t and M1 = 0.2t along the boundaries. Inset: local current distribution (E = 0.03 eV) and schematic diagram of corresponding edge states. b, c Corresponding probability distribution of edge states near the Fermi energy. d The band structure of zHNRs with the modified Haldane model under the external fields Ua = 0.2t and Ma = 0.2t. The black bands (arrows) denote the spin degeneracy case, and the red (blue) bands or arrows denote the spin-up (down) case. Other fixed parameters are the same as in Fig. 2.
