Topology and Polarization of Optical Vortex Fields from Atomic Phased Arrays
Hao Wang, Andrei Afanasev
We developed theoretical formalism for generation of optical vortices by phased arrays of atoms. Using Jacobi-Anger expansion, we demonstrate the resulting field topology and deter…

Vorticity of Twisted Spinor Fields
Andrei Afanasev, Carl E. Carlson, Asmita Mukherjee
Spinor fields with a vortex structure in free space that allow them to have arbitrary integer orbital angular momentum along the direction of motion have been studied for some time…
