Web6 Feb 2024 · Specifically, three non-spatial symmetries of the Hamiltonian — time reversal, particle–hole and chiral symmetry — sort topological insulators into ten discrete symmetry classes with distinct... WebThe celebrated tenfold way of Altland-Zirnbauer symmetry classes discern any quantum system by its pattern of nonspatial symmetries. It lays at the core of the periodic table of topological insulators and superconductors which provided a complete classification of weakly interacting electrons' noncrystalline topological phases for all symmetry classes.
