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…
Magic-angle Bilayer Phononic Graphene
Yuanchen Deng, Mourad Oudich, Nikhil JRK Gerard +3
Thanks to the recent discovery on the magic-angle bilayer graphene, twistronics is quickly becom11 ing a burgeoning field in condensed matter physics. This letter expands the realm…
Space-Time Phononic Crystals with Anomalous Topological Edge States
Mourad Oudich, Yuanchen Deng, Molei Tao +1
It is well known that an interface created by two topologically distinct structures could host nontrivial edge states that are immune to defects. In this letter, we introduce a one…
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…
Zone folding induced topological insulators in phononic crystals
Yuanchen Deng, Hao Ge, Yuan Tian +2
This letter investigates a flow-free, pseudospin-based acoustic topological insulator. Zone folding, a strategy originated from photonic crystal, is used to form double Dirac cones…
