# Renormalization of self-consistent approximation schemes at finite temperature. II. Applications to the sunset diagram

@article{Hees2001RenormalizationOS, title={Renormalization of self-consistent approximation schemes at finite temperature. II. Applications to the sunset diagram}, author={Hendrik van Hees and Joern Knoll}, journal={Physical Review D}, year={2001}, volume={65}, pages={105005} }

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 $\phi^4$-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 $\Phi$-derivable approximation or 2PI effective action concept.

We consider a symmetric scalar theory with quartic coupling in 2- and 3- dimensions and compare the self-consistent 4-point vertex obtained from the 4PI effective action with the Bethe-Salpeter…

We discuss the application of two-particle-irreducible (2PI) functional techniques to gauge theories, focusing on the issue of non-perturbative renormalization. In particular, we show how to…

We study the O(N) linear sigma model with spontaneous symmetry breaking, using a Hartree-like ansatz with a classical field and variational masses. We go beyond the Hartree approximation by including…
