Square-Root Higher-Order Exceptional Points with Symmetry-Induced Multiple Spectral Responses
Haoyang Zhang, Yadi Niu, Nuo Wang +2
We generalize square-root procedure to non-Hermitian systems with finite lattices, providing a spectral operation scheme applicable to arbitrary tight-binding models. Via this gene…

Efficient Waveform Capture without Absorption with Synthesis of Complex Frequencies
Zhaohua Tian, Yu Tian, Yadi Niu +4
A optical waveform can be synthesized by complex-frequency waves as well as by real-frequency harmonic waves. While single complex-frequency wave with exponentially rising waveform…

Enhanced Light-Matter Interactions in Dielectric Nanostructures via Machine Learning Approach
Lei Xu, Mohsen Rahmani, Yixuan Ma +9
A key concept underlying the specific functionalities of metasurfaces, i.e. arrays of subwavelength nanoparticles, is the use of constituent components to shape the wavefront of th…
