Stable and unstable perturbations in universal scaling phenomena far from equilibrium
Thimo Preis, Michal P. Heller, Jürgen Berges
We study the dynamics of perturbations around nonthermal fixed points associated to universal scaling phenomena in quantum many-body systems far from equilibrium. For an N-componen…
Collisional strong-field QED kinetic equations from first principles
Gregor Fauth, Jürgen Berges, Antonino Di Piazza
Starting from nonequilibrium quantum field theory on a closed time path, we derive kinetic equations for the strong-field regime of quantum electrodynamics (QED) using a systematic…
Thermalization and dynamical spectral properties in the quark-meson model
Linda Shen, Jürgen Berges, Jan M. Pawlowski +1
We investigate the nonequilibrium evolution of the quark-meson model using two-particle irreducible effective action techniques. Our numerical simulations, which include the full d…
Spectral, statistical and vertex functions in scalar quantum field theory far from equilibrium
Linda Shen, Jürgen Berges
We compute the far-from-equilibrium dynamics of relativistic scalar quantum fields in 3+1 space-time dimensions starting from over-occupied initial conditions. We determine univers…
Probing the evolution of heavy-ion collisions using direct photon interferometry
Oscar Garcia-Montero, Nicole Löher, Aleksas Mazeliauskas +2
We investigate the measurement of Hanbury Brown-Twiss (HBT) photon correlations as an experimental tool to discriminate different sources of photon enhancement, which are proposed…
Gauge-invariant condensation in the nonequilibrium quark-gluon plasma
Jürgen Berges, Kirill Boguslavski, Mark Mace +1
The large density of gluons, which is present shortly after a nuclear collision at very high energies, can lead to the formation of a condensate. We identify a gauge-invariant orde…
