THE PROPERTIES OF PHOTON. EXPERIMENTS AND THEORY
There are several concepts of photon used in the descriptions of optical phenomena: photon as a classical wave packet having an electrical and magnetic components; photon as a hypothetical elementary particle having a kinetic mass; photon as an excited state of the light field, determining quantum correlations of photons. The paper shows that the endowing of the physical vacuum with the properties of superfluid 3Не-В (the vacuum with such properties is referred to as the superfluid physical vacuum - SPV) makes it possible toexplain the photon properties. The magnetic properties are due to the SPV motion; the electric properties are determined by the SPV electric polarization in the vortices produced in the photon motion; the spin and kinetic mass is due to spin polarization of the vortices and the change in the inertial properties of the SPV in the vortices, respectively; quantum correlations are caused by spin supercurrent, the speed of supercurrent as an inertia free process is greater than the speed of light in the vacuum.
