Symmetry and Quantum Features in Optical Vortices

Optical vortices are beams of laser light with screw symmetry in their wavefront. With a corresponding azimuthal dependence optical phase, they convey orbital angular momentum, and methods production applications have become one the most rapidly accelerating areas physics technology. It has been established that quantum nature electromagnetic radiation extends to properties conveyed by each individual photon such beams. is therefore interest identify characterize aspects quantized fields vortex relate beam manifest its interactions matter. Chirality prominent example aspect; many other facets also invite attention. Fundamental CPT satisfied throughout field optics, it plays significantly into manifestations chirality where spatial parity broken; duality between electric magnetic involved detailed representation. From more specific considerations inversion, amongst which emerges topological charge character pseudoscalar, elements symmetry, beyond simple prove repay additional scrutiny. A photon-based perspective on these features enables regard be given salient operators, paying heed uncertainty limits observables. The analysis supports persistence significance for material beams, may indicate further scope suitably tailored experimental design.
