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…
The Classical Approximation for Real-Time Scalar Field Theory at Finite Temperature
Gert Aarts
The use of classical thermal field to approximate real-time quantum thermal field theory is discussed. For a λϕ^4 theory, it is shown that the classical Rayleigh-Jeans divergence c…
Non-Equilibrium Dynamics with Fermions on a Lattice in Space and Time
Gert Aarts, Jan Smit
We consider the dynamics of the 1+1 dimensional abelian Higgs model with axially coupled fermions, in the large N_f limit, on a lattice in space and real-time. We allow for inhomog…
Renormalizability of hot classical field theory
Gert Aarts
I discuss the possibility of using classical field theory to approximate hot, real-time quantum field theory. I calculate, in a scalar theory, the classical two point and four poin…
