Renormalization of Self-consistent Approximation schemes II: Applications to the sunset diagram
نویسندگان
چکیده
The theoretical concepts for the renormalization of self-consistent Dyson resummations, deviced in the first paper of this series, are applied to first example cases for the φ-theory. Besides the tadpole (Hartree) approximation as a novel part the numerical solutions are presented which includes the sunset self-energy diagram into the self-consistent scheme based on the Φ-derivable approximation or 2PI effective action concept.

S. Juchem, W. Cassing, C. Greiner University of Giessen, 2 University of Frankfurt The dynamics of quantum many-body systems are a challenging task for far-from-equilibrium conditions as appearing in high energy heavy-ion collisions or cosmological problems.

متن کاملRenormalization in Self-Consistent Approximation schemes at Finite Temperature I: Theory
Within finite temperature field theory, we show that truncated non-perturbative selfconsistent Dyson resummation schemes can be renormalized with local counter terms defined at the vacuum level. The requirements are that the underlying theory is renormalizable and that the self-consistent scheme follows Baym’s Φ-derivable concept. The scheme generates both, the renormalized self-consistent equa...

The understanding of quantal many-body systems is a challenging task for far-from-equilibrium conditions as appearing in high energy heavy-ion collisions or cosmological problems. It is of relevance to describe ab-initio thermalization by taking into account all quantum aspects of the particles rather than invoking semi-classical approximation schemes from the beginning [1, 2]. We here consider...

Within finite temperature field theory, we show that truncated non-perturbative self-consistent Dyson resummation schemes can be renormalized with local vacuum counterterms. For this the theory has to be renormalizable in the usual sense and the self-consistent scheme must follow Baym's Φ-derivable concept. Our BPHZ-renormalization scheme leads to renormalized self-consistent equations of motio...
