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…

Demonstration of returning Thouless pump in a Berry dipole system
Qingyang Mo, Shanjun Liang, Xiangke Lan +2
The Thouless pump, a cornerstone of topological physics, enables unidirectional quantized wave/particle transport via geometric Berry phase engineering in periodically driven syste…

Tensor-monopole-induced topological boundary effects in four-dimensional acoustic metamaterials
Qingyang Mo, Shanjun Liang, Cuicui Lu +2
Gauge field theory provides the mathematical and conceptual framework to describe and understand topological singularities such as Weyl points and magnetic monopoles. While singula…
