Authors: Vega, C.; Porras, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW RESEARCH Publication date: 2023/04/17 DOI: 10.1103/PhysRevResearch.5.023031 Abstract: Topological insulators feature a number of topologically protected boundary modes linked to the value of their bulk invariant. While in one-dimensional systems the boundary modes are zero dimensional and localized, in two-dimensional topological insulators the boundary modes are [...]
