Edge-following topological states
Guo Chuan Thiang
We prove that Chern insulators have topologically protected edge states which not only propagate unidirectionally along a straight line boundary, but also swerve around arbitrary-a…

Topological characterization of classical waves: the topological origin of magnetostatic surface spin waves
Kei Yamamoto, Guo Chuan Thiang, Philipp Pirro +3
We propose a topological characterization of Hamiltonians describing classical waves. Applying it to the magnetostatic surface spin waves that are important in spintronics applicat…

Good Wannier bases in Hilbert modules associated to topological insulators
Matthias Ludewig, Guo Chuan Thiang
For a large class of physically relevant operators on a manifold with discrete group action, we prove general results on the (non-)existence of a basis of smooth well-localised Wan…
