Realization of Topology-controlled Photonic Cavities in a Valley Photonic Crystal
Bei Yan, Baoliang Liao, Fulong Shi +11
We report an experimental realization of a new type of topology-controlled photonic cavities in valley photonic crystals by adopting judiciously oriented mirrors to localize the va…
Topological disclination states and charge fractionalization in a non-Hermitian lattice
Rimi Banerjee, Subhaskar Mandal, Yun Yong Terh +4
We show that a non-Hermitian lattice with a disclination can host topological disclination states that are induced by on-site gain and loss. The disclination states are inherently…
Photonic bilayer Chern insulator with corner states
Subhaskar Mandal, Ziyao Wang, Rimi Banerjee +6
Photonic Chern insulators can be implemented in gyromagnetic photonic crystals with broken time-reversal (TR) symmetry. They exhibit gapless chiral edge states (CESs), enabling uni…
Realization of a three-dimensional photonic higher-order topological insulator
Ziyao Wang, Yan Meng, Bei Yan +13
The discovery of photonic higher-order topological insulators (HOTIs) has significantly expanded our understanding of band topology and provided unprecedented lower-dimensional top…
Acoustic Three-dimensional Chern Insulators with Arbitrary Chern Vectors
Yang Linyun, Xi Xiang, Meng Yan +13
The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phase of three-dimensional (3D) Chern insulators. Such a vecto…
