Abstract
In this study, multipole expansion of quantum electromagnetic radiation is
constructed and quantized by canonical transformation with increasing demand
of some modern research areas of physics such as entanglement of the orbital
angular momentum states, novel experiments with trapped atoms, and the atomic
and molecular transitions with given angular momentum.
Also, the SU(2) invariance of quantum field and the rotational symmetry of
vacuum noise of polarization with respect to source location are proved.
It is shown that, at any point we can construct a proper frame in which
the description of polarization is reduced to a conventional (2 × 2) polarization
matrix. And peculiarities of electric and magnetic-type zero-point oscillations
were examined, and as a result it is shown that the monochromatic zeropoint
oscillations of all types and modes, have constant level in the volume of
quantization.
Finally, the complete local representation of photon operators, which
correspond to the states of photons with given projection of angular momentum
at any point, is constructed for the possible utility of near-field optics.
