WebJun 3, 2024 · Abstract. Starting from the phase space representation of quantum mechanics we provide an Euclidean system of covariance for the photon. In particular, we consider systems with the Poincaré group as the symmetry group and use a standard procedure in order to build a phase space and a localization observable on the phase space. Webpolarized one-photon states as (2 ) 3/2 f± (k ), cf. Eq. (3). Again, since both polarization states in Eq. (9) contribute independently (incoherently) to the total energy density, one may consider only one polarization at a time. Thus, the problem of the best localization of a …
