Query: The photon vortex beam in rotating medium   In this paper we consider the photon vortex beam in the rotating medium,
where the rotating velocity acts as an effective vector potential. Using the
Riemann-Silberstein vector, we construct the photon wave function. Using the
Maxwell equations and the first-order Minkowski constitutive relations we get
the dynamic equations of photon in moving medium. For the stationary states,
the dynamic equations can be written as a Dirac-like equation. We obtain the
approximate photon vortex beam solutions by the given the medium's different
velocity distribution and find the diffracting and nondiffracting
Laguerre-Gaussian beam solutions in the rotating medium. For the diffracting
Laguerre-Gaussian beams, we acquire new terms arising from the rotation that
can change the Gouy phase, and then accordingly infer the rotation behavior of
the photon interference pattern. Furthermore, in our theory we obtain the
Landau levels structure of transverse photon energy in the nondiffracting
Laguerre-Gaussian beam solutions.
