Multiplexed chiral and helical acoustic anomaly bulk states in an inverse-designed metamaterial
Xueyun Wen, Zhihao Lan, Zhongming Gu +2
Valley and pseudospin are fundamental degrees of freedom (DOFs) in topological acoustics. However, they have so far been realized mostly in separate systems. Here, we achieve the m…
