Rashba Spin-Orbit Driven Topological Phase Transitions in Heterogeneous Armchair Honeycomb Nanoribbons

Hao-Ru Wu, Hong-Yi Chen, Jhih-Shih You, Yiing-Rei Chen

Claims

C1strongest claim

Increasing the Rashba coupling induces symmetry-protected interface states localized at the junction between topologically distinct regions, which remain robust against edge perturbations. For finite ribbon widths, Rashba spin-orbit coupling drives a gap closing and reopening, signaling a topological phase transition without modifying the lattice structure.

C2weakest assumption

The model assumes that a Rashba spin-orbit coupled region can be cleanly embedded between pristine segments with no additional scattering or lattice distortion at the interfaces, and that the resulting interface states remain robust against realistic edge perturbations.

C3one line summary

Rashba spin-orbit coupling in graphene nanoribbon heterostructures induces symmetry-protected interface states and drives a topological phase transition through gap closing and reopening.
