Out-of-equilibrium evolution of quantum fields in the hybrid model with quantum back reaction
Jurgen Baacke, Andreas Heinen
The hybrid model with a scalar "inflaton" field coupled to a "Higgs" field with a broken symmetry potential is one of the promising models for inflation and (p)reheating after infl…

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…
