Research paperTheoreticalComputational MultiscaleExotic edge states of C₃ high-fold fermions in honeycomb latticesL. Madail, R. G. Dias, J. Fernández-RossierarXiv·2024·10.48550/arxiv.2407.08467·arXiv:2407.08467AbstractA generalization of the graphene honeycomb model to the case where each site in the honeycomb lattice contains an n-fold degenerate set of eigenstates of the C₃ symmetry has been recently proposed to describe several systems, including triangulene crystals and photonic lattices. Here, the edge states of this class of crystals are systematically studied using complete and reduced tight-binding models. The work finds dispersive edge states associated with finite-energy flat bands, bonding-antibonding pairs of dispersive edge states in non-centrosymmetric triangulene crystals, and non-dispersive zero-energy edge states in the (3,3) case.Read more
