Observation of robust intrinsic C points generation with magneto-optical bound states in the continuum
Wenjing Lv, Haoye Qin, Zengping Su +6
C points, characterized by circular polarization in momentum space, play crucial roles in chiral wave manipulations. However, conventional approaches of achieving intrinsic C point…
Extinction of guided light induced by coupled spiral meta-atom resonators at arbitrary order exceptional points
Chengzhi Zhang, Shubo Wang
Exceptional points (EPs) in non-Hermitian systems can give rise to intriguing effects not available in conventional Hermitian systems due to their unusual properties. Using full-wa…
Optical force and torque on small particles induced by polarization singularities
Jie Peng, Shiqi Jia, Chengzhi Zhang +1
Optical forces in the near fields have important applications in on-chip optical manipulations of small particles and molecules. Here, we report a study of optical force and torque…
Robust exceptional point of arbitrary order in coupled spinning cylinders
Hongkang Shi, Zheng Yang, Chengzhi Zhang +3
Exceptional points (EPs), i.e., non-Hermitian degeneracies at which eigenvalues and eigenvectors coalesce, can be realized by tuning the gain/loss contrast of different modes in no…
