With the continuous emergence of molecular and cluster devices or systems, the relationship between the plasmonic properties of multiple clusters and molecular interactions and the…
Manually Tunable Ventilated Metamaterial Absorbers
Xiang Xiao, Hongxing Tian, Yingzhou Huang +2
For most acoustic metamaterials, once they have been fabricated, their operating frequencies and functions cannot be adjusted, which is an intrinsic barrier for development of real…
Ultra-open High-efficiency Ventilated Metamaterial Absorbers with Customized Broadband Performance
Xiao Xiang, Xiaoxiao Wu, Xin Li +6
High-efficiency absorption of low-frequency sounds (< 1000 Hz) while maintaining a free flow of fluids remains a significant challenge in acoustical engineering due to the rigid tr…
Deterministic scheme for two-dimensional type-II Dirac points and experimental realization in acoustics
Xiaoxiao Wu, Xin Li, Ruo-Yang Zhang +7
Low-energy electrons near Dirac/Weyl nodal points mimic massless relativistic fermions. However, as they are not constrained by Lorentz invariance, they can exhibit tipped-over typ…
Interlayer Topological Transport and Devices based on Layer Pseudospins in Photonic Valley-Hall Phases
Xiaoxiao Wu, Zhenyu Li, Jian Chen +8
Valley-Hall phases, first proposed in two-dimensional (2D) materials, originate from nontrivial topologies around valleys which denote local extrema in momentum space. Since they a…
Su-Schrieffer-Heeger Model Inspired Acoustic Interface States and Edge States
Xin Li, Yan Meng, Xiaoxiao Wu +4
If a full band gap closes and then reopens when we continuously deform a periodic system while keeping its symmetry, a topological phase transition usually occurs. A common model d…
