Majorana stellar representation of twisted photons

Physical Review Research is a fully open access, peer-reviewed, international, multidisciplinary journal covering all research topics of interest to the physics community. Its July - September 2023 issue includes ‘Majorana stellar representation of twisted photons’, an article by Andrei B. Klimov, Romain Murenzi, Jean-Pierre Gazeau, and Luis L. Sánchez-Soto. As the article’s abstract explains,
Majorana stellar representation, which visualizes a quantum spin as points on the Bloch sphere, allows quantum mechanics to accommodate the concept of trajectory, the hallmark of classical physics. We extend this notion to the discrete cylinder, which is the phase space of the canonical pair angle and orbital angular momentum. We demonstrate that the geometrical properties of the ensuing constellations aptly encapsulate the quantumness of the state.
