From Chern to Winding: Topological Invariant Correspondence in the Reduced Haldane Model
Ghassan Al-Mahmood, Mohsen Amini, Ebrahim Ghanbari-Adivi +1
We present an exact analytical investigation of the topological properties and edge states of the Haldane model defined on a honeycomb lattice with zigzag edges. By exploiting tran…

Backscattering of topologically protected helical edge states by line defects
Mohadese Karimi, Mohsen Amini, Morteza Soltani +1
The quantization of conductance in the presence of non-magnetic point defects is a consequence of topological protection and the spin-momentum locking of helical edge states in two…
