Chiral plasmons with twisted atomic bilayers
Xiao Lin, Zifei Liu, Tobias Stauber +5
Van der Waals heterostructures of atomically thin layers with rotational misalignments, such as twisted bilayer graphene, feature interesting structural moiré superlattices. Due to…
Realization of an acoustic third-order topological insulator
Haoran Xue, Yahui Yang, Guigeng Liu +3
The recent discovery of higher-order topological insulators (TIs) has opened new possibilities in the search for novel topological materials and metamaterials. Second-order TIs hav…
Spin-valley-controlled photonic topological insulator
Haoran Xue, Fei Gao, Yang Yu +3
The discovery of photonic topological insulators (PTIs) has opened the door to fundamentally new topological states of light.Current time-reversal-invariant PTIs emulate either the…
Acoustic higher-order topological insulator on a Kagome lattice
Haoran Xue, Yahui Yang, Fei Gao +2
High-order topological insulators (TIs) are a family of recently-predicted topological phases of matter obeying an extended topological bulk-boundary correspondence principle. For…
Superlight inverse Doppler effect
Xihang Shi, Xiao Lin, Ido Kaminer +5
There is a century-old tenet [1, 2] that the inverse Doppler frequency shift of light [3-13] is impossible in homogeneous systems with a positive refractive index. Here we break th…
Sorting and Routing Topologically Protected Edge States by their Valleys
Kueifu Lai, Yang Yu, Yuchen Han +3
We experimentally demonstrate and characterize a photonic platform containing heterogeneous topological phases. This platform is shown to support valley-spin locked edge states tha…
