Parametric amplification versus collisions: An illustrative application
D. Ahrensmeier, R. Baier, M. Dirks
We investigate the time dependence of the quantum statistical model with self-interaction and consider the resulting induced particle number density. For a special exampl…
Dynamical screening in hot systems away from (chemical) equilibrium
R. Baier, M. Dirks, K. Redlich
Within the Closed Time Path Formalism of Thermal Field Theory we calculate the hard photon emission rate as well as the collisional energy-loss rate for a quark-gluon plasma away f…
Dynamical screening away from equilibrium: hard photon production and collisional energy loss
R. Baier, M. Dirks, K. Redlich
We investigate the production rate for hard real photons and the collisional energy loss in the quark-gluon plasma away from chemical equilibrium. Applying the Hard-Thermal-Loop re…
Anomalous electromagnetic processes at high temperatures
R. Baier, M. Dirks, O. Kober
Chiral theories of constituent quarks interacting with bosons and photons at high temperatures are studied. In the expected chirally symmetric phase effective electromagnetic anoma…
