SPIN OF A PHOTON AND POLARISATION STATES OF LIGHT WAVE

The photon is a boson, so when a number of photons are in the same state, the wave functions that describe the photons in quantum physics are precisely the same as the Maxwell's equations of macroscopic electromagnetic fields. In this paper we discuss in detail the relations between the selection rules in atomic physics and the parity conserva-tion selection rules on the one hand, and the photon spin on the other. We also explain that the positron annihilation theory and experiments have offered a proof for the correctness of the theoretical analysis of the photon spin. Moreover. we give a brief introduction to the relation between the polarization state of the light wave and the spin state of the photon from both macroscopic and microscopic aspects. We also introduce the virtual photon theo-ry, Aharonov-Bohm effect, the relations between the geometric phase on the one hand, and the photon spin and the light beam polarization on the other. Thus, we present some new points of view for the further study of the photon nature. In the References the paper"The Supersymmentry of the Photon"is listed for further study.
