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…

Chiral switching of elastic spin via dynamic encirclement of exceptional points
Chenwen Yang, Shubo Wang
Dynamically encircling exceptional points (EPs) enables chiral state conversion in classical wave systems. However, whether this mechanism can be extended to chiral spin conversion…

Dynamically encircling exceptional points: in situ control of encircling loops and the role of the starting point
Xu-Lin Zhang, Shubo Wang, Bo Hou +1
The most intriguing properties of non-Hermitian systems are found near the exceptional points (EPs) at which the Hamiltonian matrix becomes defective. Due to the complex topologica…
