Physical rendering of synthetic spaces for topological sound transport
Hui Chen, Hongkuan Zhang, Qian Wu +5
Synthetic dimensions can be rendered in the physical space and this has been achieved with photonics and cold atomic gases, however, little to no work has been succeeded in acousti…
Channel-Coupling Fano Resonance and Acoustic Metadamping
Huy Nguyen, Qian Wu, Hui Chen +1
Fano resonance featuring asymmetric spectral profiles originates from the interference of local resonances and background continuum. Its narrow-band nature looks seemingly adverse…
Microtwist elasticity: A continuum approach to zero modes and topological polarization in Kagome lattices
Hussein Nassar, Hui Chen, Guoliang Huang
The topologically polarized isostatic lattices discovered by Kane and Lubensky (2014, Nat. Phys. 10, 39-45) challenged the standard effective medium theories used in the modeling o…
Elastic quantum spin-Hall effect in Kagome lattices
Hui Chen, Hussein Nassar, Andrew N. Norris +2
A Quantum Spin-Hall Insulator (QSHI) is implemented into a simple mass-spring Kagome lattice. The transition from the trivial state to the topological one is described by an invari…
Observation of nonreciprocal wave propagation in a dynamic phononic lattice
Yifan Wang, Behrooz Yousefzadeh, Hui Chen +3
Acoustic waves in a linear time-invariant medium are generally reciprocal; however, reciprocity can break down in a time-variant system. In this Letter, we report on an experimenta…
Topological mechanics of edge waves in Kagome lattices
Hui Chen, Hussein Nassar, Guoliang Huang
Topological insulators are new phases of matter whose properties are derived from a number of qualitative yet robust topological invariants rather than specific geometric features…
