Generation and high-resolution imaging of higher-order polarization via metasurface
Xiang Yuan, Hanming Guo, Songlin Zhuang +1
The generation and focusing properties of higher-order polarized beams have attracted lots of interests due to its significant applications. In this paper,we derived the formula of…
Higher-Order Topological Insulators via Momentum-Space Nonsymmorphic Symmetries
Jinbing Hu, Songlin Zhuang, Yi Yang
The topology of the Brillouin zone, foundational in topological physics, is always assumed to be a torus. We theoretically report the construction of Brillouin real projective plan…
Synthetic non-Abelian gauge fields for non-Hermitian systems
Zehai Pang, Jinbing Hu, Yi Yang
Non-Abelian gauge fields are versatile tools for synthesizing topological phenomena but have so far been mostly studied in Hermitian systems, where gauge flux has to be defined fro…
Decomposition of Abraham momentum into complex orbital and spin momenta in evanescent wave
Hu Jinbing, Zhuang Songlin, Guo Hanming
The Abraham momentum of electromagnetic field represents the decomposition property into real-valued orbital and spin contributions. However, we found that the orbital and spin mom…
