Optimizing multi-user indoor sound communications with acoustic reconfigurable metasurfaces
Hongkuan Zhang, Qiyuan Wang, Mathias Fink +1
Sound in indoor spaces forms a complex wavefield due to multiple scattering encountered by the sound. Indoor acoustic communication involving multiple sources and receivers thus in…
Non-Abelian physics in light and sound
Yi Yang, Biao Yang, Guancong Ma +3
There has been a recent surge of interest in using light and sound as platforms for studying non-Abelian physics. Through a kaleidoscope of physical effects, light and sound provid…
Realization of a Z classified chiral-symmetric higher-order topological insulator in a coupling-inversion acoustic crystal
Dongyi Wang, Yuanchen Deng, Mourad Oudich +3
Higher-order topological band theory has transformed the landscape of topological phases in quantum and classical systems. Here, we experimentally demonstrate a two-dimensional (2D…
Experimental realization of stable exceptional chains protected by non-Hermitian latent symmetries unique to mechanical systems
Xiaohan Cui, Ruo-Yang Zhang, Xulong Wang +3
Lines of exceptional points are robust in the 3-dimensional non-Hermitian parameter space without requiring any symmetry. However, when more elaborate exceptional structures are co…
Experimental Realization of Geometry-Dependent Skin Effect in a Reciprocal Two-Dimensional Lattice
Wei Wang, Mengying Hu, Xulong Wang +2
Recent studies of non-Hermitian periodic lattices unveiled the non-Hermitian skin effect (NHSE), in which the bulk modes under the periodic boundary conditions (PBC) become skin mo…
