On the Wave Function of the Photon
... I shall introduce a wave function for the photon by reviving and extending the mode of description of the electromagnetic field based on the complex form of the Maxwell equations. This form was known already at the beginning of the century [8,9] and was later rediscovered by Majorana [10] who explor ...
