A Canonical Relativistic Approach to Quantize Electromagnetic Field in   the Presence of Moving Magneto-Dielectric Media
  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 four vectors 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 tensor of the third rank which couples the electromagnetic field with the medium is introduced and the susceptibility tensor of the medium is obtained in terms of the coupling tensor. Also the noise polarization tensor is calculated in terms of the coupling tensor and the creation and annihilation operators of the four vectors modeling the medium.
