DOI: 10.1063/5.0221895

Abstract: We proposed a method to measure the topological charge of a vortex beam by using the self-rotating beam phase in this Letter. We investigated the far-field intensity patterns of the vortex beams passing through a… read more here.

DOI: 10.1103/ln96-7j68

Abstract: Traditionally applied within equilibrium states, the charge-vortex dualities are expanded to address the complex dynamics of superfluids and ideal fluids under nonstatic conditions. We have constructed explicit mappings of finite temperature fluid dynamics to gauge… read more here.

DOI: 10.1364/ol.43.002780

Abstract: We demonstrate for the first time, to the best of our knowledge, the ability of extreme ultraviolet (XUV) Hartmann wavefront sensors to characterize high charge vortex beams produced by high-order harmonic generation up to the… read more here.

DOI: 10.3788/col202119.022603

Abstract: Encoding information using the topological charge of vortex beams has been proposed for optical communications. The conservation of the topological charge on propagation and the detection of the topological charge by a receiver are significant… read more here.
