Entanglement, excitations and correlation effects in narrow zigzag graphene nanoribbons
I. Hagymasi, O. Legeza
We investigate the low-lying excitation spectrum and ground-state properties of narrow graphene nanoribbons with zigzag edge configurations. Nanoribbons of comparable widths have b…

Characterization of a correlated topological Kondo insulator in one dimension
I. Hagymasi, O. Legeza
We investigate the ground-state of a p-wave Kondo-Heisenberg model introduced by Alexandrov and Coleman with an Ising-type anisotropy in the Kondo interaction and correlated conduc…
