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…
Breakdown of diffusivity-entropy scaling in colloidal glass forming liquids
Bo Li, Xiuming Xiao, Shuxia Wang +2
Glass is a liquid that has lost its ability to flow. Why this particular substance undergoes its dramatic slowing down in kinetics while remaining barely distinguishable in structu…
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…
