Riemann-Silberstein geometric phase in 4D polarization space
Yuqiong Cheng, Yuan-Song Zeng, Wanyue Xiao +5
Geometric phase is a far-reaching concept in quantum and classical physics. The first discovered geometric phase, the Pancharatnam-Berry (PB) phase, has profoundly shaped nanophoto…
Directional sources realised by toroidal dipoles
Junho Jung, Yuqiong Cheng, Wanyue Xiao +1
Directional optical sources can give rise to the directional excitation and propagation of light. The directionality of the conventional directional dipole (CDD) sources are attrib…
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…
Optical isolation induced by subwavelength spinning particle via spin-orbit interaction
Hongkang Shi, Yuqiong Cheng, Zheng Yang +2
Optical isolation enables nonreciprocal manipulations of light with broad applications in optical communications. Optical isolation by rotating structures has drawn considerable at…
