Non-singular and singular flat bands in tunable acoustic metamaterials [PDF]
Phys. Rev. Research 5, 023036 (2023), 2022 Dispersionless flat bands can be classified into two types: (1) non-singular flat bands whose eigenmodes are completely characterized by compact localized states; and (2) singular flat bands that have a discontinuity in their Bloch eigenfunctions at a band touching point with an adjacent dispersive band, thereby requiring additional extended states to ...
