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…
A simple scheme to realize the Rice-Mele model in acoustic system
Tianzhi Xia, Xiying Fan, Qi Chen +2
The Rice-Mele (RM) model, as a paradigmatic extension of the Su-Schrieffer-Heeger (SSH) chain, plays a pivotal role in understanding topological phases and quantized adiabatic tran…
Observation of Anti-helical Edge States in Acoustic Metamaterials
Tianzhi Xia, Qicheng Zhang, Chunyin Qiu
As a hallmark of the quantum Hall effect, chiral edge modes (CEMs) counterpropagate along the two parallel edges of a ribbon structure. However, recent studies demonstrate counteri…
Observation of Hybrid-Order Topological Pump in a Kekule-Textured Graphene Lattice
Tianzhi Xia, Yuzeng Li, Qicheng Zhang +3
Thouless charge pumping protocol provides an effective route for realizing topological particle transport. To date, the first-order and higher-order topological pumps, exhibiting t…
Tracking valley topology with synthetic Weyl paths
Xiying Fan, Tianzhi Xia, Huahui Qiu +2
Inspired by the newly emergent valleytronics, great interest has been attracted to the topological valley transport in classical metacrystals. The presence of nontrivial domain-wal…
