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…
Topology with memory in nonlinear driven-dissipative photonic lattices
Subhaskar Mandal, Gui-Geng Liu, Baile Zhang
We consider a photonic lattice of nonlinear lossy resonators subjected to a coherent drive, where the system remembers its topological phase. Initially, the system is topologically…
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…
