Phys. Rev. A 71, 033816 (2005) [4 pages]Angular momentum and the geometrical gauge of localized photon statesReceived 30 July 2004; published 24 March 2005 We have examined the physical meaning of the geometric gauge associated with the photon position operator and find that localized photon states are not spherically symmetric and may have orbital angular momentum and optical vortices determined by the choice of gauge. © 2005 The American Physical Society URL:
