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…
