Originally formulated in the context of condensed matter physics, the Haldane model is an influential model of a two-dimensional topological insulator. It has also been realized in classical-wave metamaterial analogues of topological insulator, such as photonic crystals, acoustic crystals, and electric LC circuits.
Recently, theorists have shown that a modification to the Haldane model exhibits the novel phenomenon of antichiral edge sates, according to E. Colomés and M. Franz, scholars at Department of Physics and Astronomy and Quantum Matter Institute, University of British Columbia. Unlike the chiral edge states associated with the standard Haldane model, antichiral edge states possess the same propagation dire
