Spatiotemporal Vortex Rings Induced by Spatiotemporal Coupling
Zhiling Zhou, Wei Zhong, Tong Fu +4
Vortices and vortex rings are topological structures that arise in various physical systems. However, the generation of spatiotemporal vortices (STVs) and vortex rings (STVRs) has…
Real-space Hybrid Topological Singularities in Structured Elastic Waves
Tong Fu, Pengfei Zhao, Liyou Luo +5
Real-space singularities govern a broad spectrum of wave phenomena, yet they remain largely unexplored in elastic wave systems. Here, we report hybrid topological singularities tha…
Acoustic helical dichroism enhanced by chiral quasi-bound states in the continuum
Qing Tong, Tong Fu, Yuqiong Cheng +1
Acoustic helical dichroism (HD) arises from the interaction between vortex beams carrying orbital angular momentum (OAM) and chiral media, yet such chiral sound-matter interactions…
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…
Optical force and torque on a spinning dielectric sphere
Hengzhi Li, Wanyue Xiao, Tong Fu +2
Optical force can enable precise manipulations of small particles for various applications. It is well known that an isotropic lossless dielectric sphere is only subject to forward…
Optical polarization singularities in metallic cavities excited by electric dipole sources
Shiqi Jia, Tong Fu, Shubo Wang
Optical polarization singularities (PSs) in real space carry rich topological properties and can enable highly precise manipulations of light fields. Conventional studies focus on…
Topological Dark Spots of Electric Near Field in Metal Structures
Tong Fu, Qing Tong, Shiqi Jia +1
Electric dark spots are point singularities at which the electric field amplitude vanishes. These singularities usually emerge in real space accidentally and are unstable due to th…
Near-field Spin Chern Number Quantized by Real-space Topology of Optical Structures
Tong Fu, Ruo-Yang Zhang, Shiqi Jia +2
The Chern number has been widely used to describe the topological properties of periodic structures in the momentum space. Here, we introduce a real-space spin Chern number for the…
