Real-space Formalism for the Euler Class and Fragile Topology in Quasicrystals and Amorphous Lattices
Dexin Li, Citian Wang, Huaqing Huang
We propose a real-space formalism of the topological Euler class, which characterizes the fragile topology of two-dimensional systems with real wave functions. This real-space desc…

Liganded Xene as a Prototype of Two-Dimensional Stiefel-Whitney Insulators
Mingxiang Pan, Dexin Li, Jiahao Fan +1
Two-dimensional (2D) Stiefel-Whitney insulator (SWI), which is characterized by the second Stiefel-Whitney class, is a new class of topological phases with zero Berry curvature. As…
