An exact renormalization group approach to frustrated magnets

Frustrated magnets are a notorious example where usual perturbative methods fail. Having recourse to an exact renormalization group approach, one gets a coherent picture of the physics of Heisenberg frustrated magnets everywhere between d = 2 and d = 4: all known perturbative results are recovered in a single framework, their apparent conflict is explained while the description of the phase transition in d = 3 is found to be in good agreement with the experimental context.
