Activation function optimization method: Learnable series linear units (LSLUs)
Chuan Feng, Xi Lin, Shiping Zhu +3
Effective activation functions introduce non-linear transformations, providing neural networks with stronger fitting capa-bilities, which help them better adapt to real data distri…
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…
Gauge-field description of Sagnac frequency shift and mode hybridization in a rotating cavity
Hongkang Shi, Zhongfei Xiong, Weijin Chen +3
Active optical systems can give rise to intriguing phenomena and applications that are not available in conventional passive systems. Structural rotation has been widely employed t…
