Query: Real Time Nonequilibrium Dynamics of Quantum Plasmas. Quantum Kinetics
  and the Dynamical Renormalization Group   We implement the dynamical renormalization group (DRG) using the hard thermal
loop (HTL) approximation for the real-time nonequilibrium dynamics in hot
plasmas. The focus is on the study of the relaxation of gauge and fermionic
mean fields and on the quantum kinetics of the photon and fermion distribution
functions. As a concrete physical prediction, we find that for a QGP of
temperature T sim 200 MeV and lifetime 10 < t < 50 fm/c there is a new
contribution to the hard (k \sim T) photon production from off-shell
bremsstrahlung (q rightarrow q gamma and bar{q} rightarrow bar{q} gamma) at
just O (alpha) that grows logarithmically in time and is comparable to the
known on-shell Compton scattering and pair annihilation at O(alpha alpha_s).
