Anomalous multi-ramp fractional vortex beams with arbitrary topological charge jumps
Jun Zeng, Zhiheng Xu, Chengliang Zhao +2
Traditional fractional vortex beams are well-known "jump" beams: that is, their net topological charge jumps by unity as the effective topological charge of the source passes a hal…

Correlation-induced orbital angular momentum changes
Yongtao Zhang, Olga Korotkova, Yangjian Cai +1
We demonstrate that the orbital angular momentum flux density of a paraxial light beam can change on propagation in free space. These changes are entirely due to the spatial cohere…
