Non-Hermitian skin effect (NHSE) is a prominent feature in non-Hermitian physics, leading
to novel topological properties and expanding the traditional energy band theories. In this …

Topological phases in photonic microring lattices with projective symmetry

Y Liu, C Jiang, W Wen, Y Song, X Li, P Lu, S Ke - Physical Review A, 2024 - APS
Symmetry plays a key role in classifying topological phases, which can be enriched by the
projective symmetry group in the presence of artificial gauge fields (AGFs). Here, we utilize …
