Circularly polarized states spawning from bound states in the continuum
Wenzhe Liu, Bo Wang, Yiwen Zhang +6
Bound states in the continuum in periodic photonic systems like photonic crystal slabs are proved to be accompanied by vortex polarization singularities on the photonic bands in th…
Realizing data features by deep nets
Zheng-Chu Guo, Lei Shi, Shao-Bo Lin
This paper considers the power of deep neural networks (deep nets for short) in realizing data features. Based on refined covering number estimates, we find that, to realize some c…
Observation of optical states below light cone with compound lattices
Jiajun Wang, Ang Chen, Maoxiong Zhao +5
For optical systems, states inside the light cone could be detected by far-field measurement, while those below the light cone are not detectable by far-field measurement. A new me…
Fast and Strong Convergence of Online Learning Algorithms
Zheng-Chu Guo, Lei Shi
In this paper, we study the online learning algorithm without explicit regularization terms. This algorithm is essentially a stochastic gradient descent scheme in a reproducing ker…
Topological phase transition and interface states in hybrid plasmonic-photonic systems
Lixin Ge, Liang Liu, Meng Xiao +5
The geometric phase and topological property for one-dimensional hybrid plasmonic-photonic crystals consisting of a simple lattice of graphene sheets are investigated systematicall…
Nonconvex Sorted Minimization for Sparse Approximation
Xiaolin Huang, Lei Shi, Ming Yan
The norm is the tight convex relaxation for the "norm" and has been successfully applied for recovering sparse signals. For problems with fewer samplings, one nee…
Enhanced light-matter interaction in graphene-covered gold nanovoid arrays
Xiaolong Zhu, Lei Shi, Michael S. Schmidt +5
The combination of graphene with noble-metal nanostructures is currently being explored for strong light-graphene interaction enhanced by plasmons. We introduce a novel hybrid grap…
