Zhujun Ye is a PhD student at quantum theory group at University of Glasgow. Her research topic mainly lies on structured light, including strongly focussing of vector vortex beams and Skyrmions. She has done several relevant projects during the 3 years of PhD, one examined the (secondary) Faraday effect under strong focussing, which exhibits more subtlety in rotating the polarization structure after the beam has been focussed, the relevant paper is now being written. As for Skyrmions, she has found a generalization which allows measurements of Skyrmion numbers not to be limited on Schmidt bases; this has been proved to improve the precision in experimental measurements (McWilliam et al., 2022). Currently, she is looking into a further generalization of the current 2D Skyrmion model to a 3D one, and has found solid tools to characterize 3D polarization.
