A Short Course on Topological Insulators: Band Structure and Edge States in One and Two Dimensions
TL;DR: In this paper, a course-based primer provides newcomers to the field with a concise introduction to some of the core topics in the emerging field of topological band insulators in one and two dimensions.
Journal ArticleDOI
Computable measure of nonclassicality for light.
TL;DR: The entanglement potential detects nonclassicality, has a direct physical interpretation, and can be computed efficiently, which make it stand out from previously proposed non classicality measures.
Journal ArticleDOI
Bulk-boundary correspondence for chiral symmetric quantum walks
János K. Asbóth,Hideaki Obuse +1 more
TL;DR: In this article, the authors define chiral symmetry for discrete-time quantum walks (DTQW) and show that CS can be ensured by using an ''inversion symmetric'' pulse sequence.
Journal ArticleDOI
Chiral symmetry and bulk{boundary correspondence in periodically driven one-dimensional systems
TL;DR: In this article, the authors calculate topological invariants for chiral symmetric periodically driven one-dimensional systems and show that these invariants can be tuned using sublattice shifts.
