Annihilation of Dirac points and its topological obstruction in a photonic Kagome lattice
Zhaoyang Zhang, Matthieu Finck, Changchang Li +7
Dirac points (DPs) are topological singularities that determine the extraordinary properties of two-dimensional materials. They are generally classified by discrete topological inv…

Dirac points annihilation and its obstruction characterized by Euler number and quaternionic charges in kagome lattice
M. Finck, D. Solnyshkov, J. Dubois +1
We investigate the topological phenomenon of Dirac point annihilation and its obstruction in three-band, real symmetric Hamiltonians with time-reversal symmetry, and their relation…
