    An elegant experiment showing that acoustic waves are amplified after scattering by a rotating body demonstrates an effect predicted in 1971 by Yakov Zel’dovich. This result has implications for the understanding of scattering from black holes.

    Higher-order topological acoustic metamaterials on kagome lattices, which host topologically protected corner states, can confine sound at corners. This may lead to applications of acoustic metamaterials in local acoustic field enhancement, trapping and manipulating of particles, and acoustic sensing and probing.
