Phononic real chern insulator
WebHere, we study phonons in 2D graphyne family materials. By using first-principle calculations and topology/symmetry analysis, we find that phonons in both graphdiyne and $\gamma$ … WebFeb 24, 2024 · Although graphyne is not a conventional topological insulator because of its weak spin–orbit coupling, it is a real Chern topological insulator with the higher-order topology. However, it lacks a realistic model. Here, we propose a schedule to realize acoustic graphyne.

We can also calculate the Chern number using the low-energy Hamiltonian. At Δ = − 2, the energy gap collapses at the Γ = (0, 0) point, near this point, we have. HΓ + k = kxσx + kyσy + (Δ + 2)σz. For the Hamiltonian H(k) = kxσx + kyσy + mσz, we can get the monopole field for E − state is.
