Dynamical aspects of photon acceleration
We present here a review of recent work concerning the theory of photon acceleration in space and time varying plasmas. We will focus our atention on the dynamical aspects of the photon ray tracing equations and discuss the possible regimes of regular and stochastic photon acceleration. Photon trapping by an electron plasma wave and a model for photon Fermi acceleration will be presented. Our approach will be based on the Hamiltonian canonical equations for photons. A covariant Hamiltonian description will also be discussed.
