Chiral topology
WebThe value of \(Q\) specifies the number of chiral edge states and their chirality, which is opposite for opposite signs of \(Q\). A \(2\mathbb{Z}\) ... In fact, we know another way to change the dimensionality while preserving the topology. It is … WebApr 30, 2024 · I don't know much about topology, but the other day I was thinking about the (classic?) coffee cup - donut topological equivalence. I realised that a cylinder with one open end and a handle on the side (a mug) is a chiral object in 3D space, whereas a torus/donut is achiral ("meso", as indicated by the internal planes of symmetry present in a torus).
