The paper presents interesting studies on tunable higher-order topological states of acoustic systems. A 3D structure based on an in-plane Kagome lattice and an out-of-plane Su-Schrieffer-Heeger chain is proposed, that by engineering couplings in different dimensions can simultaneously host 2D surface states, 1D hinge states and 0D corner states.

Controlling audible sound requires inherently broadband and subwavelength acoustic solutions. Exploiting the unique physics of plasmacoustic metalayers, we experimentally demonstrate versatile and tunable sound control over a wide frequency range.

Collisions between two individual electrons in a quantum nanoelectronic circuit revealed a mutual interaction fully mediated by Coulomb repulsion—an essential building block for two-qubit logic implementations with flying electrons.

Reciprocity is a standard characteristic of acoustic wave transmission but breaking the symmetry can lead to greater control and potential applications. Here, the authors report non-reciprocal acoustics by achieving large breaking of reciprocity in sounds composed of harmonics spanning several octaves via non-Hermitian physics.
