Kirigami-based Flexible Metasurface with Reconfigurable Intrinsic Chirality from Zero to Near-unity
Yiyi Yao, Shijie Kang, Aoning Luo +7
Chiral responses in electromagnetic metasurfaces are typically categorized as extrinsic, resulting from asymmetric interactions between the structure and incident waves, and intrin…
Hybrid Cavity from Tunable Coupling between Anapole and Fabry-Perot Resonance or Anti-resonance
Aoning Luo, Haitao Li, Ken Qin +8
Enhancing light-matter interactions depends critically on the ability to tailor photonic modes at subwavelength scales, and combining distinct resonant modes has shown remarkable p…
Giant and Rapidly Switching Intrinsic Chirality Enabled by Toroidal Quasi-Bound States in the Continuum
Shijie Kang, Jiusi Yu, Boyuan Ge +8
Circular dichroism (CD), arising from spin-selective light-matter interactions controlled by chirality, is critical for advanced applications such as chiral imaging and ultrasensit…
Direct Observation of Strongly Tilted Dirac Points at General Positions in the Reciprocal Space
Yangsong Ye, Shijie Kang, Jiusi Yu +7
Type-II Dirac points (DPs), which occur at the intersection of strongly tilted and touching energy bands, exhibit many intriguing physical phenomena fundamentally different from th…
