WebIn this theoretical work, we formulate hyperbolic versions of two paradigm topological tight-binding models, namely of (1) the Haldane model of Chern insulator, and of (2) the Kane-Mele model of time-reversal-symmetric topological insulator. These modifications are achieved by replacing the hexagonal cells of the honeycomb lattice by octagons. Web14 mrt. 2024 · Hyperbolic Topological Band Insulators.

Web23 mei 2024 · Interestingly, a topological insulator like Bi2Se32, as well as heterostructures like graphene/hBN 3, can support coexisting polaritonic waves of all the kinds stated above. WebA topological insulator is an insulator whose Hamiltonian cannot be adiabatically connected to the atomic limit. Adiabatic means that, when tuning some external parameter (e.g. pressure, temperature) to change the Hamiltonian, the process is slow enough that the material stays in its ground state throughout.
