Observation of Polarization Topology in Magneto-Optical BICs
Yaqi Li, Mingyu Tong, Fujia Chen +7
Polarization topology in momentum space is a fundamental characteristic of photonic bound states in the continuum (BICs), where the winding of far-field polarization defines a quan…
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…
Boundary-induced topological chiral extended states in Weyl metamaterial waveguides
Ning Han, Fujia Chen, Mingzhu Li +9
In topological physics, it is commonly understood that the existence of the boundary states of a topological system is inherently dictated by its bulk. A classic example is that th…
