Multiple scattering theory of non-Hermitian sonic second-order topological insulators
Rosendo López, María; Zhang, Zhiwang; Torrent, Daniel; Christensen, Johan (2019-10-25)Topological phases of sound enable unconventional confinement of acoustic energy at the corners in higher-order topological insulators. These unique states which go beyond the conventional bulk-boundary correspondence have ...
