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 Fully Flat Bands in a Photonic Dipolar Kagome Lattice
Han-Rong Xia, Ziyao Wang, Yunrui Wang +2
Flat bands, characterized by zero group velocity and strong energy localization, enable interaction-enhanced phenomena across both quantum and classical systems. Existing photonic…
