Observation of Custodial Chiral Symmetry in Memristive Topological Insulators
Wenhao Li, Junyao Wu, Ning Han +8
The concept of custodial symmetry, a residual symmetry that protects physical observables from large quantum corrections, has been a cornerstone of high-energy physics, but its exp…
Realization of Weyl elastic metamaterials with spin skyrmions
Yuang Pan, Liang Si, Miao Yang +18
Topological elastic metamaterials provide a topologically robust way to manipulate the phononic energy and information beyond the conventional approaches. Among various topological…
Photonic antiferromagnetic topological insulator with a single surface Dirac cone
Fujia Chen, Ning Han, Songyang Pu +12
Antiferromagnetism, characterized by magnetic moments aligned in alternating directions with a vanished ensemble average, has garnered renewed interest for its potential applicatio…
Three-dimensional topological valley photonics
Wenhao Li, Qiaolu Chen, Ning Han +8
Topological valley photonics, which exploits valley degree of freedom to manipulate electromagnetic waves, offers a practical and effective pathway for various classical and quantu…
