Constructing Exceptional Knots and Links with Arbitrary Braiding Topology
Bin Jiang, Aolong Guo, Qilin Cai +1
Exceptional knots and links represent a remarkable class of non-Hermitian metals in which exceptional degeneracies form knotted or linked manifolds in momentum space. Here, we repo…
Entanglement dynamics driven by topology and non-Hermiticity
Li-Wei Wang, Bolun Hu, Haixiao Zhang +3
The interplay between topology and non-Hermiticity gives rise to exotic dynamic phenomena that challenge conventional wave-packet propagation and entanglement dynamics. While recen…
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…
Non-Hermitian glide-time symmetry
Li-Wei Wang, Jian-Hua Jiang
Non-Hermitian systems, going beyond conventional Hermitian systems, have brought in intriguing concepts such as exceptional points and complex spectral topology as well as exotic p…
Topological thermal transport
Zhoufei Liu, Peng Jin, Min Lei +4
Thermal transport is a fundamental mechanism of energy transfer process quite distinct from wave propagation phenomena. It can be manipulated well beyond the possibilities offered…
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…
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…
Observation of topology transition in Floquet non-Hermitian skin effects in silicon photonics
Zhiyuan Lin, Wange Song, Li-Wei Wang +7
Non-Hermitian physics has greatly enriched our understanding of nonequilibrium phenomena and uncovered novel effects such as the non-Hermitian skin effect (NHSE) that has profoundl…
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…
Controlling mass and energy diffusion with metamaterials
Fubao Yang, Zeren Zhang, Liujun Xu +9
Diffusion driven by temperature or concentration gradients is a fundamental mechanism of energy and mass transport, which inherently differs from wave propagation in both physical…
