Vortex formation around islands in random waves
Alex J. Vernon, Junyi Ye, Wenzhe Liu +2
Wave vortices are fundamental topological features of interference fields, occurring at nodal points where the wave amplitude vanishes. A distinct class of vortices can instead for…
Wave Vortices Around Oscillating Subwavelength Holes: Water-Wave Observation
Junyi Ye, Zheyi Li, Alexey Y. Nikitin +4
We consider a two-dimensional wave system containing a subwavelength hole, such as an aperture in an interface supporting surface electromagnetic or acoustic waves, or an island in…
Emerging Multidimensional Real-Space Topological Structures at Chiral Bound States in the Continuum
Xingqi Zhao, Jingguang Chen, Jiajun Wang +6
As widely studied topological singularities, bound states in the continuum (BICs) have revealed rich physical properties through their momentum-space topology. Here, we reveal and…
Dynamic Water-Wave Tweezers
Jun Wang, Shanhe Pang, Zhiyuan Che +11
Following a recent demonstration of stable trapping of floating particles by stationary (monochromatic) structured water waves [Nature 638, 394 (2025)], we report dynamic water-wav…
Meron Spin Textures in Momentum Space Spawning from Bound States in the Continuum
Lixi Rao, Jiajun Wang, Xinhao Wang +7
Topological spin textures, such as merons and skyrmions, have shown significance in both fundamental science and practical applications across diverse physical systems. The optical…
Topological Singularities in Metasurface Scattering Matrices: From Nodal Lines to Exceptional Lines
Jingguang Chen, Wenzhe Liu, Jiajun Wang +6
Topological properties of photonic structures described by Hamiltonian matrices have been extensively studied in recent years. Photonic systems are often open systems, and their co…
Bulk-spatiotemporal vortex correspondence in gyromagnetic double-zero-index media
Ruo-Yang Zhang, Xiaohan Cui, Yuan-Song Zeng +8
Photonic double-zero-index media, distinguished by concurrently zero-valued permittivity and permeability, exhibit extraordinary properties not found in nature. Remarkably, the not…
Spin-Orbit-Locking Chiral Bound States in the Continuum
Xingqi Zhao, Jiajun Wang, Wenzhe Liu +5
Bound states in the continuum (BICs), which are confined optical modes exhibiting infinite quality factors and carrying topological polarization configurations in momentum space, h…
Generation of Spatiotemporal Vortex Pulses by Simple Diffractive Grating
Zhiyuan Che, Wenzhe Liu, Lei Shi +2
Spatiotemporal vortex pulses are wave packets that carry transverse orbital angular momentum, exhibiting exotic structured wavefronts that can twist through space and time. Existin…
Topological Polarization Singularities in Metaphotonics
Wenzhe Liu, Wei Liu, Lei Shi +1
Polarization singularities of vectorial electromagnetic fields locate at the positions (such as points, lines, or surfaces) where properties of polarization ellipses are not define…
