Tunable Antichiral Hinge State in Photonic Synthetic Dimensions
Xian-Hao Wei, Xi-Wang Luo, Mu Yang +4
Recent research in 2-dimensional (2D) topological matter has generalized the notion of edge states from chiral to antichiral configurations with the same propagating direction at p…

Higher-order Topological Parity Anomaly and Half-integer Hall Effect in High-dimensional Synthetic Lattices
Xian-Hao Wei, Xi-Wang Luo, Guang-Can Guo +1
Recent advances in constructing synthetic dimension provide a powerful tool for exploring exotic topological states of matter in high dimensions. Here we report that the parity ano…
