Temporal Branched Flow of Light
Weifeng Ding, Chaokai Yang, Zhaoying Wang +1
Branched flow of light arises when spatially correlated disorder folds families of rays into caustics. Here, we demonstrate a temporal analog in the retarded-time coordinate of an…

Geometric spin Hall effect of spatiotemporal optical vortices
Chaokai Yang, Weifeng Ding, Zhaoying Wang
The geometric spin Hall effect of light (GSHEL), which is associated with nonzero transverse angular momentum, has been demonstrated to occur without the need for light-matter inte…
