Transport, Aharonov-Bohm, and Topological Effects in Graphene Molecular Junctions and Graphene Nanorings
Constantine Yannouleas, Igor Romanovsky, Uzi Landman
The unique ultra-relativistic, massless, nature of electron states in two-dimensional extended graphene sheets, brought about by the honeycomb lattice arrangement of carbon atoms i…
Interplay of relativistic and nonrelativistic transport in atomically precise segmented graphene nanoribbons
Constantine Yannouleas, Igor Romanovsky, Uzi Landman
Graphene's isolation launched explorations of fundamental relativistic physics originating from the planar honeycomb lattice arrangement of the carbon atoms, and of potential techn…
Beyond the constant-mass Dirac physics: Solitons, charge fractionization, and the emergence of topological insulators in graphene rings
Constantine Yannouleas, Igor Romanovsky, Uzi Landman
The doubly-connected polygonal geometry of planar graphene rings is found to bring forth topological configurations for accessing nontrivial relativistic quantum field (RQF) theory…
Topological effects and particle-physics analogies beyond the massless Dirac-Weyl fermion in graphene nanorings
Igor Romanovsky, Constantine Yannouleas, Uzi Landman
Armchair and zigzag edge terminations in planar hexagonal and trigonal graphene nanorings are shown to underlie one-dimensional topological states associated with distinctive energ…
Graphene flakes with defective edge terminations: Universal and topological aspects, and one-dimensional quantum behavior
Igor Romanovsky, Constantine Yannouleas, Uzi Landman
Systematic tight-binding investigations of the electronic spectra (as a function of the magnetic field) are presented for trigonal graphene nanoflakes with reconstructed zigzag edg…
Patterns of the Aharonov-Bohm oscillations in graphene nanorings
Igor Romanovsky, Constantine Yannouleas, Uzi Landman
Using extensive tight-binding calculations, we investigate (including the spin) the Aharonov-Bohm (AB) effect in monolayer and bilayer trigonal and hexagonal graphene rings with zi…
