Cet exposé présente des résultats récents [17, 18] quant à deux modèles effectifs pour les effets de la polarisation du vide quantique sur les champs électromagnétiques. Le modèle de Pauli-Villars les décrit de manière rigoureuse lorsque les champs électromagnétiques sont supposés classiques. À partir de ce premier modèle est ensuite proposée une dérivation du modèle classique d’Euler-Heisenberg [22] dans un régime de champs purement magnétiques et faiblement variables.
