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…
Designing topological interface states in phononic crystals based on the full phase diagrams
Yan Meng, Xiaoxiao Wu, Ruo-Yang Zhang +8
The topological invariants of a periodic system can be used to define the topological phase of each band and determine the existence of topological interface states within a certai…
Type-II Dirac photons at the metasurfaces
Chuandeng Hu, Zhenyu Li, Rui Tong +9
Topological characteristics of energy bands, such as Dirac/Weyl nodes, have attracted substantial interest in condensed matter systems as well as in classical wave systems. Among t…
High-efficiency Ventilated Metamaterial Absorber at Low Frequency
Xiaoxiao Wu, Ka Yan Au-Yeung, Xin Li +7
We demonstrate a ventilated metamaterial absorber operating at low frequency (< 500 Hz).With only two layers of the absorption units, high-efficiency absorption (> 90%) has been ac…
