Observation of higher-order exceptional points in a non-local acoustic metagrating
Xinsheng Fang, Nikhil JRK Gerard, Zhiling Zhou +7
Higher-order exceptional points have attracted increased attention in recent years due to their enhanced sensitivity and distinct topological features. Here, we show that nonlocal…
Bilayer Photonic Graphene
Mourad Oudich, Guangxu Su, Yuanchen Deng +6
Drawing inspiration from bilayer graphene, this paper introduces its photonic analog comprising two stacked graphene-like photonic crystals, that are coupled in the near-field thro…
Guiding Robust Valley-dependent Edge States by Surface Acoustic Waves
Zhen Wang, Fu-Kang Liu, Si-Yuan Yu +4
Recently, the concept of valley pseudospin, labeling quantum states of energy extrema in momentum space, has attracted enormous attention because of its potential as a new type of…
