Non-Gaussian anomalous diffusion of optical vortices
J Gong, Q Li, S Zeng, J Wang - Physical Review E, 2024 - APS
Anomalous diffusion of different particlelike entities, the deviation from typical Brownian
motion, is ubiquitous in complex physical and biological systems. While optical vortices …

Anomalous diffusion of optical vortices in random wavefields
J Gong, Q Li, J Wang - arxiv preprint arxiv:2303.07690, 2023 - arxiv.org
We investigate the dynamic behavior of optical vortices, or phase singularities, in random
wavefields and demonstrate the direct experimental observation of the anomalous diffusion …

Two-dimensional quantitative near-field phase imaging using square and hexagonal interference devices
We demonstrate the formation of the near field with non-trivial phase distribution using
surface plasmon interference devices, and experimental quantitative imaging of that phase …
