Nonequilibrium Fields: Exact and Truncated Dynamics
Gert Aarts
The nonperturbative real-time evolution of quantum fields out of equilibrium is often solved using a mean-field or Hartree approximation or by applying effective action methods. In…

Exact and Truncated Dynamics in Nonequilibrium Field Theory
Gert Aarts, Gian Franco Bonini, Christof Wetterich
Nonperturbative dynamics of quantum fields out of equilibrium is often described by the time evolution of a hierarchy of correlation functions, using approximation methods such as…

On Thermalization in Classical Scalar Field Theory
Gert Aarts, Gian Franco Bonini, Christof Wetterich
Thermalization of classical fields is investigated in a ϕ^4 scalar field theory in 1+1 dimensions, discretized on a lattice. We numerically integrate the classical equations of mot…
