Nonequilibrium evolution of Phi**4 theory in 1+1 dimensions in the 2PPI formalism
Jurgen Baacke, Andreas Heinen
We consider the out-of-equilibrium evolution of a classical condensate field and its quantum fluctuations for a Phi**4 model in 1+1 dimensions with a symmetric and a double well po…

The O(N) linear sigma model at finite temperature beyond the Hartree approximation
J. Baacke, S. Michalski
We study the O(N) linear sigma model with spontaneous symmetry breaking, using a Hartree-like ansatz with a classical field and variational masses. We go beyond the Hartree approxi…
