Phononic real chern insulator

WebFractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue towards manipulating non-Abelian excitations. Early theoretical studies 1-7 have predicted their existence in systems with flat Chern bands and highlighted the critical role of a particular quantum geometry. 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 $\gamma$ …
