Divergences in Real-Time Classical Field Theories at Non-Zero Temperature
Gert Aarts, Bert-Jan Nauta, Chris G. van Weert
The classical approximation provides a non-perturbative approach to time-dependent problems in finite temperature field theory. We study the divergences in hot classical field theo…
Real-time dynamics in the 1+1 D abelian Higgs model with fermions
G. Aarts, J. Smit
In approximate dynamical equations, inhomogenous classical (mean) gauge and Higgs fields are coupled to quantized fermions. The equations are solved numerically on a spacetime latt…
Particle Production and Effective Thermalization in Inhomogeneous Mean Field Theory
Gert Aarts, Jan Smit
As a toy model for dynamics in nonequilibrium quantum field theory we consider the abelian Higgs model in 1+1 dimensions with fermions. In the approximate dynamical equations, inho…
Dynamics of Fermions and Inhomogeneous Bose Fields on a Real-Time Lattice
Gert Aarts, Jan Smit
The dynamics of the 1+1 abelian Higgs model with fermions is studied in the large N_f approximation, on a real-time lattice. The Bose fields obey effective classical equations of m…
