Topological metasurface: From passive toward active and beyond
Jian Wei You, Zhihao Lan, Qian Ma +5
Metasurfaces are subwavelength structured thin films consisting of arrays of units that allow the controls of polarization, phase and amplitude of light over a subwavelength thickn…
Demonstration of broadband topological slow light
Fujia Chen, Haoran Xue, Yuang Pan +12
Slow-light devices are able to significantly enhance light-matter interaction due to the reduced group velocity of light, but a very low group velocity is usually achieved in a nar…
Spinful topological phases in acoustic crystals with projective PT symmetry
Yan Meng, Shuxin Lin, Bin-jie Shi +14
For the classification of topological phases of matter, an important consideration is whether a system is spinless or spinful, as these two classes have distinct symmetry algebra t…
Perovskite quantum dot topological laser
Jingyi Tian, Qi Ying Tan, Yutao Wang +4
Various topological laser concepts have recently enabled the demonstration of robust light-emitting devices that are immune to structural deformations and tolerant to fabrication i…
Observation of Dirac hierarchy in three-dimensional acoustic topological insulators
Linyun Yang, Yin Wang, Yan Meng +12
Dirac cones (DCs) play a pivotal role in various unique phenomena ranging from massless electrons in graphene to robust surface states in topological insulators (TIs). Recent studi…
Discovery of a maximally charged Weyl point
Qiaolu Chen, Fujia Chen, Qinghui Yan +7
The hypothetical Weyl particles in high-energy physics have been discovered in three-dimensional crystals as collective quasiparticle excitations near two-fold degenerate Weyl poin…
