The Pauli-Lubanski Vector, Complex Electrodynamics, and Photon Helicity
Abstract
We critically analyze the concept of photon helicity and its connection with the Pauli-Lubanski vector from the viewpoint of the complex electromagnetic field, F=E+iH, sometimes attributed to Riemann but studied by Weber, Silberstein, and Minkowski. To this end, a complex form of Maxwell's equations is used.
