The dynamics of cosmological perturbations in thermal theory
Herbert Nachbagauer, Anton K. Rebhan, Dominik J. Schwarz
Using a recent thermal-field-theory approach to cosmological perturbations, the exact solutions that were found for collisionless ultrarelativistic matter are generalized to includ…

The gravitational polarization tensor of thermal theory
H. Nachbagauer, A. K. Rebhan, D. J. Schwarz
The low-momentum structure of the gravitational polarization tensor of an ultrarelativistic plasma of scalar particles with interactions is evaluated in a two-loop calculati…

The Infrared Sensitivity of Screening and Damping in a Quark-Gluon Plasma
F. Flechsig, A. K. Rebhan, H. Schulz
All the next-to-leading order contributions to the quasi-particle dispersion laws of a quark-gluon plasma which due to infrared singularities are sensitive to the magnetic-mass sca…
