Figure | Schematic illustration of the multi-topological phase (MTP) and its associated bulk-boundary correspondence. MTP is a new type of topological phase of matter, defined in a periodic lattice system (represented by the white frame) that features multiple topological invariants (W1, W2 and W3, illustrated as different colored doughnuts), each associated with its own set of topological boundary states (illustrated with colors corresponding to topological invariant).
