Time-Reversal-Invariant Altermagnetic Acoustic Crystals
Tianzhi Xia, Han-Rong Xia, Jinglin Liu +3
Altermagnets have emerged as a new class of magnetic materials that combine spin-split electronic bands with zero net magnetization. Extending this paradigm to classical-wave syste…
Observation of Antichiral Hinge States in a Three-dimensional Gyromagnetic Photonic Crystal
Ziyao Wang, Tianzhi Xia, Han-Rong Xia +1
Recent advances in topological physics have revealed a counterintuitive class of antichiral edge and surface states that propagate in the same direction along spatially separated p…
Observation of biased random-flux-induced topological phase transition in gyromagnetic photonic crystals
Hai-Xiao Wang, Chongyang Li, Xianmu Wu +5
The paper experimentally demonstrates a disorder‑driven topological phase transition in gyromagnetic photonic crystals by randomly orienting the magnetization of rods, creating a b…
Observation of fractality-induced topology in photonic crystals
Bei Yan, Yingfeng Qi, Xiang Xi +6
Fractal topology--achieved by integrating nontrivial topology into fractal geometries with self-similarity and non-integer dimensions--has opened new avenues for exploring topologi…
Crosstalk-free Chiral Anomaly Bulk States in Photonic Crystals
Guochao Wei, Yingfeng Qi, Kang Du +5
Ultracompact cladding-free waveguide arrays with zero inter-channel spacing and negligible crosstalk open a new avenue for high-density integrated photonic circuits. However, exist…
Spatiotemporal topological phase transitions in photonic spacetime crystals
Zebin Zhu, Bolun Huang, Siqi Xu +5
Topological phase transitions, characterized by the closing and reopening of band gaps and a concomitant change in topological invariants, have played a central role in topological…
