Renormalized thermodynamics from the 2PI effective action
J. Berges, Sz. Borsanyi, U. Reinosa +1
High-temperature resummed perturbation theory is plagued by poor convergence properties. The problem appears for theories with bosonic field content such as QCD, QED or scalar theo…
Kinetic equilibration in heavy ion collisions: the role of elastic processes
Julien Serreau
We discuss the question of thermalization during the very early stages of a high energy heavy ion collision. We review a recent study where we explicitely showed that, contrarily t…
Far-from-equilibrium dynamics with broken symmetries from the 2PI-1/N expansion
G. Aarts, D. Ahrensmeier, R. Baier +2
We derive the nonequilibrium real-time evolution of an O(N) - invariant scalar quantum field theory in the presence of a nonvanishing expectation value of the quantum field. Using…
Kinetic equilibration in heavy ion collisions: The role of elastic processes
J. Serreau, D. Schiff
We study the kinetic equilibration of gluons produced in the very early stages of a high energy heavy ion collision in a ``self-consistent'' relaxation time approximation. We compa…
On the microscopic dynamics of DCC formation
J. Serreau
The dynamics of the pion field after a quench is studied in the framework of the linear sigma model. Our aim is to determine to what extent the amplified pion field resembles the D…
