Renormalized Finite Temperature phi^4 theory from the 2PI Effective Action
A. Arrizabalaga, U. Reinosa
We present an analytical and numerical study of scalar phi^4 theory at finite temperature with a renormalized 2-loop truncation of the 2PI effective action.
Kinetic and Chemical Equilibration in Scalar phi^4 Theory
Alejandro Arrizabalaga
Approximations based on the 2PI effective action are used to investigate the process of equilibration in phi^4 theory in 3+1 dimensions, both in the symmetric and broken phase. A s…
Equilibration in phi^4 theory in 3+1 dimensions
Alejandro Arrizabalaga, Jan Smit, Anders Tranberg
The process of equilibration in phi^4 theory is investigated for a homogeneous system in 3+1 dimensions and a variety of out-of-equilibrium initial conditions, both in the symmetri…
Tachyonic preheating using 2PI-1/N dynamics and the classical approximation
Alejandro Arrizabalaga, Jan Smit, Anders Tranberg
We study the process of tachyonic preheating using approximative quantum equations of motion derived from the 2PI effective action. The O(N) scalar (Higgs) field is assumed to expe…
