Dynamics of Transverse Spin and Longitudinal Fields of Cylindrical Vector Beams in Optically Active Media
Yuanyang Xie, Alexey Krasavin, Anatoly V. Zayats +1
Due to the inhomogeneous polarisation across the beam profile, cylindrical vector beams interact with optically active media in a complex manner. Here, we analyse evolution of pola…

Universal nondiffractive topological spin textures in vortex cores of light and sound
Elena Annenkova, Andrei Afanasev, Etienne Brasselet
We report universal skyrmionic spin textures in the cores of optical and acoustic vortex beams, described within the framework of Laguerre-Gaussian modes. We analytically demonstra…
