Realization of edge states along a synthetic orbital angular momentum dimension
Yu-Wei Liao, Mu Yang, Hao-Qing Zhang +8
The synthetic dimension is a rising method to study topological physics, which enables us to implement high-dimensional physics in low-dimensional geometries. Photonic orbital angu…

Realization of exceptional points along a synthetic orbital angular momentum dimension
Mu Yang, Hao-Qing Zhang, Yu-Wei Liao +7
Exceptional points (EPs), at which more than one eigenvalue and eigenvector coalesce, are unique spectral features of Non-Hermiticity (NH) systems. They exist widely in open system…
