Pseudo topological insulators

Publication date: Available online 22 October 2018Source: Physics Letters AAuthor(s): C. YuceAbstractWe predict pseudo topological insulators that have been previously overlooked. We determine some conditions under which robust pseudo topological edge states appear and illustrate our idea on the Su–Schrieffer–Heeger (SSH) model with extra chiral symmetry breaking potentials. We discuss that pseudo topological insulating phase transition occurs without band gap closing.
