Cubic edge dispersion in a semi-Dirac Chern insulator
Marta GarcÃa Olmos, David MartÃn Tejedor, Mario Amado +2
Topological edge states in Chern insulators are typically characterized by a linear dispersion relation inherited from the Dirac structure of the bulk Hamiltonian. Here we show tha…

High order momentum topological insulator in 2D semi-Dirac materials
Marta GarcÃa Olmos, Yuriko Baba, Mario Amado +1
Semi-Dirac materials in 2D present an anisotropic dispersion relation, linear along one direction and quadratic along the perpendicular one. This study explores the topological pro…
