Topological Phases in Graphene Nanoribbons: Junction States, Spin Centers, and Quantum Spin Chains

We show that semiconducting graphene nanoribbons (GNRs) of different width, edge, and end termination (synthesizable from molecular precursors with atomic precision) belong to different electronic topological classes. The topological phase of GNRs is protected by spatial symmetries and dictated by t...
