Query: Real-time Nonequilibrium Dynamics in Hot QED Plasmas   The quantum kinetics of photons is studied directly in real time by
implementing the dynamical renormalization group. In contrast to conventional
approach, the dynamical renormalization group method consistently includes
off-shell (energy non-conserving) effects and accounts for time-dependent
collisional kernel. To lowest order we find that in the relaxation time
approximation the semihard photon distribution function relaxes with a power
law.
