Le 14 novembre 2013 à 16h15 en B107, James Ryan nous parlera de : Melons are branched polymers

Résumé : Melonic graphs constitute the family of graphs arising at leading order in the 1/N expansion of tensor models. They were shown to lead to a continuum phase, reminiscent of branched polymers. We show here that they are in fact precisely branched polymers, that is, they possess Hausdorff dimension 2 and spectral dimension 4/3.
