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…
Twisted multilayer moiré water waves topologically robust to disorder
Zhiyuan Che, Julian Schwab, Yi Zhang +6
Moiré patterns, stacking and twisting multilayer periodic lattices into superlattices, have become cornerstones of many physical systems from condensed matter to wave phenomena, b…
Quasi-bound flat bands in the continuum
Haoyu Qin, Weixuan Zhang, Shaohu Chen +6
Bound states in the continuum (BICs) are widely known spatially localized states experimentally implemented as quasi-BICs. Although they emerged as a promising solution for achievi…
Vectorial microlasers with designable topological charges based on Möbius-like correspondence in quasi-BICs
Xinhao Wang, Zhaochen Wu, Jiajun Wang +2
The ability to control topological properties of laser emission represents a fundamental advancement in photonic technology. Achieving topological laser in a single compact photoni…
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…
