Two-loop solution of the O(N) model from 2PI effective potential



I will speak about the complete two-loop solution of the O(N) model in 2PI formalism. First I will present the non-perturbative renormalisation of the approximation, then I will show the algorithm of solving the self-consistent equations numerically. The latest numerical results will also be presented.
