Topological Switch between Second-Order Topological Insulators and Topological Crystalline Insulators

Physical Review Letters, 2018
We investigate a topological switch between second-order topological insulators (SOTIs) and topological crystalline insulators (TCIs). Both the SOTI and the TCI are protected by the mirror and inversion symmetries, for which we define the bulk topological numbers of the same type. We take examples of square nanodisks on the square lattice and hexagonal

Quartic-root higher-order topological insulators on decorated three-dimensional sonic crystals

APL Materials
The square-root operation provides a new scheme to create topological phases with unconventional spectrum properties. With the square-root operation, the square-root topological insulators can support paired topological boundary states in two bulk gaps ...

Photonic axion insulator with non-coplanar chiral hinge transport

Nature Communications
Axion insulators represent a unique class of magnetic topological phases, linking the two-dimensional quantum anomalous Hall effect to the magnetic higher-order phase of three-dimensional topological insulators.
