WebDec 14, 2024 · Topological insulators, on the other hand, are characterized by non-local and quantized topological invariants that cannot change continuously. The most experimentally relevant kinds of topological insulators are therefore characterized by an insulating (gapped) bulk and a conducting (gapless) boundary.
