Abstract: | A canonical relativistic formulation is introduced to quantize
electromagnetic field in the presence of a polarizable and
magnetizable moving medium. The medium is modeled by a continuum of
the second rank antisymmetric tensors in a phenomenological way. The
covariant wave equation for the vector potential and the covariant
constitutive equation of the medium are obtained as the Euler-Lagrange equations using the Lagrangian of the total system.
A
fourth rank tensor which couples the electromagnetic field and the
medium is introduced. The susceptibility tensor of the medium is
obtained in terms of this coupling tensor. The noise polarization
tensor is calculated in terms of both the coupling tensor and the
ladder operators of the tensors modeling the medium. |
