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…

Solid-State Gravitational Redshift: Transport Signatures of Massless Dirac Fermions in Tilted Dirac Cone Heterostructures
Marziyeh Karmand, Mohsen Amini, Morteza Soltani +2
We investigate the propagation of electron waves in a two-dimensional tilted Dirac cone heterostructure where tilt depends on the coordinate along the junction. The resulting D…
