Optical Lattices with Higher-order Exceptional Points by Non-Hermitian Coupling
Xingping Zhou, Samit Kumar Gupta, Zhong Huang +5
Exceptional points (EPs) are degeneracies in open wave systems with coalescence of at least two energy levels and their corresponding eigenstates. In higher dimensions, more comple…
Experimental Observation of Acoustic Weyl Points and Topological Surface States
Hao Ge, Xu Ni, Yuan Tian +6
Weyl points emerge as topological monopoles of Berry flux in the three-dimensional (3D) momentum space and have been extensively studied in topological semimetals. As the underlyin…
Parity-Time Symmetry in Non-Hermitian Complex Optical Media
Samit Kumar Gupta, Yi Zou, Xue-Yi Zhu +4
The explorations of the quantum-inspired symmetries in optical and photonic systems have witnessed immense research interests both fundamentally and technologically in a wide range…
Topological Flat Band and Parity-Time Symmetry in a Honeycomb Lattice of Coupled Resonant Optical Waveguides
Xue-Yi Zhu, Samit Kumar Gupta, Xiao-Chen Sun +6
Two-dimensional (2D) coupled resonant optical waveguide (CROW), exhibiting topological edge states, provides an efficient platform for designing integrated topological photonic dev…
