Unveiling spin-orbital angular momentum locking in photonic Dirac vortex cavities
Haitao Li, Jiusi Yu, Jiayu Fan +6
Dirac vortices, originally studied in quantum field theories to predict localized zero-energy modes, were recently realized in photonics, leading to Dirac vortex cavities. With top…
Quadrupole topological behavior of elastic waves in two-dimensional square lattices with nonsymmorphic symmetries
Yijie Liu, Yuyang Chen, Zhaoyang Guo +4
We investigate a novel higher-order topological behavior in elastic lattices characterized by nonsymmorphic symmetries. In the theoretical spring-mass lattice, altering the vertex…
Observation of a -orbital higher-order topological insulator phase in puckered lattice acoustic metamaterials
Bing-Quan Wu, Zhi-Kang Lin, Li-Wei Wang +1
The puckered lattice geometry, along with -orbitals is often overlooked in the study of topological physics. Here, we investigate the higher-order topology of the -orbi…
Non-Hermitian topological phases and skin effects in kagome lattices
Li-Wei Wang, Zhi-Kang Lin, Jian-Hua Jiang
Non-Hermitian physics has added new ingredients to topological physics, leading to the rising frontier of non-Hermitian topological phases. In this study, we investigate Chern insu…
Probing fragile topology with a screw dislocation
Ying Wu, Zhi-Kang Lin, Yating Yang +3
Fragile topology, akin to twisted bilayer graphene and the exotic phases therein, is a notable topological class with intriguing properties. However, due to its unique nature and t…
Measuring entanglement entropy and its topological signature for phononic systems
Zhi-Kang Lin, Yao Zhou, Bin Jiang +6
Entanglement entropy is a fundamental concept with rising importance in different fields ranging from quantum information science, black holes to materials science. In complex mate…
